I've got a working ML installation using whitegerry's 7zip file for mountain lion. The steps I took to do the install are as follows:
1) create unibeast usb drive
2) copy the files from the "Pre installation/Extra" folder in the 7zip file into the Extra folder on the unibeast disk and copy the files from the "SLE" folder to the System/Library/Extensions" folder on the unibeast disk.
3) boot off the USB disk, format internal drive, perform installation
4) boot off USB again, use the terminal to copy the files from the "SLE" folder of the 7z file to System/Library/Extensions on the internal hard drive, copy the files from the "Extra" folder of the 7z into a new directory "Extra" on the internal hard drive.
5) use the USB disk to boot the internal hard drive. BE SURE TO BOOT WITH THE -x OPTION. Finish the installation, install Chimera with MultiBeast.
6) Boot into ML.
The only issues I'm having are the inability to recognize the internal trackpad as a trackpad in the preferences pane and some random graphical corruption on sleep.

And you need to update the nvidia driver to fix the grahpics issues(extract the kext files with pacifist):http://www.nvidia.com/object/macosx-304.00.00f20-driver.html

Okay. I got all the files from whitegerry, and it all seems to work well. Although I am not so sure about the performance. HWMonitor shows the cpu goes only up to 1.86 Ghz (it's the i7 740QM) instead of almost 3Ghz it should. I wouldn't care too much as that could be just false reporting, but I ran those benchmarks guys here did (novabench) and I am getting quite lower scores there...
All,
I have an L501x with 10.8.3 installed using whitegerry's Mountain Lion files. Thank you very very much whitegerry!!!!! I was wondering if you or anyone who has had a successful installation, is having problem with USB 3.0 port? My USB 2.0 ports works perfectly, but when I plug in USB 3.0 specific devices, (i.e. External HDD, USB Flash), my system will not recognize it. Any kexts or tweaks to get it working? Any help is always much appreciated.
Thank you in advance.
