It's shorter to note what doesn't work.
1. SD Card
1. Sleep - closing the lid doesn't put laptop to sleep. Need to manually do it.
How I did it.
1. Purchase Mountain Lion
2. Create a USB Installer using Unibeast 1.5.1 * laptop specific
3. Installed and Rebooted without encountering problems.
4. Run Multibeast
- user DSDT
- system utilities
- ps/2 kb and trackpad
- macbook pro 8,1 system definitions
5. After Multibeast
- edited org.chameleon.Boot.plist
- removed ncpi=0x3000
- removed kernel cache
- removed legacy logo
6. Installed using KtextWizard
- AppleACPIBatteryManager & AppleSmartBatteryManager (battery support)
- AtherosL1cEthernet (for LAN support)
* sleep enabler instruction on the next post.
* credits to Lion installation of archintosh where I derived most of the files.

ktext wizard is a part of multi beast.
and yes, qe quarts is working flawlessly. before mountain lion, i used to have snow leopard and have screen tearing occasionally. with mountain lion, this problem seem to be fixed oob.
I'd definitely like to give a shout-out to both you and archintosh. I have a similar system and have gotten it to about 90% using his DSDTs and your guides. Have been using it for about two weeks [super busy with class] and am getting features one by one.
Thanks again! You've been a huge help.
For anyone that's interested (if this belongs in another thread, let me know and I'll move it):
Intel Sandy Bridge i5 2450M @ 2.5 Ghz
8 GB 1333 MHz DDR3
Intel HD 3000 (512 MB)
750 GB HD
Mountain Lion 10.8.0 (haven't had the courage to do the update yet - will do that later)
-Standard Unibeast install (Note: I had issues here with the USB drive. I tried a 8.0 GB old flash drive, and it didn't work. I borrowed a Kensington 16 GB DataTraveler from a friend and it worked great)
There are two semi-working ways to get this done. Archintosh has been kind enough to post two DSDTs: The first (Called 3 Page, because it's from his three page thread here) works well but doesn't have sound.
The second (called January 2012 from here) has sound but takes some tweaking to get VGA-out to work.
-Installed 3 Page DSDT but ended up replacing it with January 2012 AppleHDA stuff to get sound to work. This broke VGA out, but everything else seems to be okay.
-When all else fails, I make one change at a time, and see if that fixes or breaks it. It's a long process, but I'm a n00b and have no idea what I'm doing.
-Installed the SleepEnabler ktext above. Used KtextUtility; seems to be more reliable.
Doing Archintosh's January 2012 setup works, but I did HDA.ktext and replaced DSDT to get working sound. I will be adding brightness control later (in minutes) and trying to get Intel SNB working again (my notes say that this method actually worked, so I need to figure out what changed).
Again, it's easiest to list what doesn't work:
-VGA out (can't test HDMI out till later; my parents' TV is a dinosaur) [doesn't cause crash, but isn't recognized and external monitor stays blank]
-Trackpad scrolling / multitouch [I would LOVE to get Mac OS to recognize my trackpad so I can check "Ignore Accidental Trackpad Input"! My thumb touches the trackpad occasionally]
-Messages! WTF. Can't sign in.
-Sleep doesn't work on lid close, but great otherwise.
-battery: Battery seems to last 3 - 3.5 hours vs. 4 hours on Windows [Speedstepping?]
Monitor, native resolutions.
Sound + keyboard control, automagically switches to headphone jack (30% of time needs to try again, but usually works)
Keyboard, mouse [including right button!].
WiFi [occasionally craps out, but only on my parents' SUPER LAME router. School is fine. Also, works after sleep, which is something people were worried about]
Dual Boot Windows 7 via Chameleon [two partitions; 500 GB Mac and 250 GB Windoze]
-Microphone for webcam [am downloading Skype to check]
-Speedstepping. Terminal 'yes' gives me a positive result, but I simply don't know anything about it. My feeling is that Archintosh's installation includes the P and C states, so I'm thinking that might be the case.
A BIG note: Apple's Time Machine Backup is -great-. If at any point I broke the installation, I'd backup. If I got something working and wanted to make sure it stayed that way, I made a backup. I think I only had to do two hard restores; the rest were fixed by safe mode and removing the most recent ktext modification.
So, again: CHEERS to you guys for getting my machine working! Not a bad machine for $390 all said and done.
I used unibeast and have successfully installed mountain lion 10.8. This has taken me about six months. I was finally able to get my hands on a real Mac book to make a USB installer.
During the installation I had to use the boot flags -x and GraphicsEnabler=No, or I was presented with a black screen soon after seeing a grey screen.
The problem is that when I now boot into the successfully installed OS, I get the black screen again. It continues to load the OS as I can see the hard drive still being accessed, but I don't get to see the fruit. Just a black screen.
I tried the same boot flags, also none, and also just -x. Same result.
I disabled switchable graphics in the BIOS.
When I bought the G470 they added some extra RAM (total now 8GB). I don't know if that's relevant or not.
