Try adding your video card's device ID to NVDAResman.kext (if it's an Nvidia video card)

Also try booting in 32-bit mode.

How do i do that? :X

To boot in 32-bit mode type arch=i386 at the bootprompt if you're using Chameleon, or -x32 if you're using PC_EFI.

 

To edit a kernel extension, copy it from /System/Library/Extensions to your desktop, of course you should also make a backup copy of it to another folder.

 

Right click it and click 'show contents' to open it, then open the info.plist inside in a plist editor (google for one or install Apple XCode to get one).

 

Find where the device IDs are and look for yours. You can copy the whole line of device IDs into a text document and search them if that's easier for you.

If you don't find your video cards device ID there, then, following the same syntax as the other ones that are already there, insert the device ID of your video card. You should be able to see the device ID under 'Graphics/Displays' in System Profiler.

 

After making your modifications, save the plist and copy the kext back to /System/Library/Extensions, overwriting the old one.

 

Then fix permissions. Read this: http://apple2pc.blogspot.com/2008/04/all-about-kext.html

 

Good luck.
