OK! Some tips then.
One of the most mysterious things that can go wrong is getting the patched kext into the right place, with the right permissions, so I follow the standard process with kextbeast:
1) copy the kext to the Desktop
2) duplicate it so you have a backup (but move it somewhere since kextbeast will install the duplicate, too!)
3) edit the copy of the kext on the Desktop
4) launch kextbeast, which handles all of the installation details, replacing the original in /S/L/E
-- For the actual patching, I use 0xED because it's easy to use and free, but if you already have a favorite it shouldn't make a difference.
-- Yes, since the kext is a "package" you have to open the unix executable file within it, in your hex editor:
/Users/XXX/Desktop/AppleIntelFramebufferAzul.kext/Contents/MacOS/AppleIntelFramebufferAzul
As I explained in the above post you just need to locate that "OLD" sequence, which only appears once in the file, and change 3 of the bytes.
Now, for the mac-pixel-clock-patch, it's at
https://code.google.com/r/darkvoid-mac-pixel-clock/source/browse/macPixelClockPatcher.command
There are basically 2 commands there, on lines 5 and 6. You can open up a terminal and just paste them in one-by-one in order so you don't even have to download it. But there is a gotcha here, too. On a fresh machine you probably don't have the 'codesign' utility installed. However, OS X will prompt you for that installation so that the command will run. You can even run line 6 a second time for good measure if you lost your terminal window during the install process for some reason.
One more important thing! Forgive me if it's obvious but you are installing a PATCHED kext here. So you absolutely HAVE to have "kext-dev-mode=1" in your kernel flags (I have it in org.chameleon.Boot.plist). I hate to be overly blunt but if you're not familiar with this aspect of patching then I hesitate to recommend this procedure.
All in all, though, it's pretty foolproof, and at worst rebooting into safe mode and restoring the original AppleIntelFramebufferAzul.kext
Hope this helps, if there's anything unclear let me know.
