But unfortunately graphics acceleration does not seem to be working. Animations are choppy and the itunes visualizer does not display. I've tried the patches to the Geforce drivers that worked with my card in 10.7, but mountain lion does not seem to like them. Any advice is appreciated.
This is a work machine so I'll gladly paypal $5 to anyone who provides a working solution.

Edit org.chameleon.boot.plist with a tool like Champlist and check/uncheck GE=Y/N to see in which case it's working
Try to edit AppleGraphicsPowerManagement.kext by putting your correct GPU device id's in .plist.

Thanks for the reply. I am using chameleon and have already modified
org.chameleon.boot.plist to toggle GE (No GE causes a black screen, GE + no EFI causes a white screen, EFI and any GE setting lets me boot without acceleration). I just modifiedAppleGraphicsPowerManagement.kext but that had no effect.

i don't know if this can help you, but try to add your ID into Info.plist from NVDAGF100Hal.kext (S/L/E)
Repair the permissions, reboot ! Pray !

neotrunks: I don't think that's for GTX cards.

When making the installer itself, I added the string in NVDAGF100Hal.kext and placed my smbios.plist from hardware acclerated OS X Lion in the extra folder on the disc. While in installation itself, I got full resolution....

Just One update I would like to add is, The Stock Mountain Lion doesn't have Geforce.kext present in Lion. Can everyone please try pasting this geforce.kext in extensions of your installed mountain lion, add the graphic card string in NVDAGF100HAL.kext, repair permissions, for safely, use netkas fakesmc (Found it completely working)....
ML has no PS2 support I suppose, So add appropriate kexts..(They differ from machine to machine.)...
Now cross your fingers and reboot. Please post your replies on my post. Hope this works for all of you.....

Only Neo got it working or everyone out here has...??????
Mine works 100%....
No blue screen when resolution is changed.....
When I shut down my computer, it doesn't really shut down...
The CPU LED stays on...
The Fans and Graphic Card Exhaust stays on.
I have to restart my computer to turn it off....

*By "us", I am referring to other forums besides this one (sigh! yes 'that one' too) Not much responses to issues on here lately so I end up where Google takes me... which has not been much use.

and Sid, to be honest i found loads of ways to make the 550ti work with QE/QL but i didn't know how and i think i fixed it by mistake.. all i did was follow this website here http://thetecherra.c...rt-to-finish-2/
then it wouldn't boot up i was suck on usbmsc identifier in -v mode... then i ran the bootloader again and added to the bootloader the resolution for my card and my monitor and bam it worked.. no plist editing to the NVAD100 or anything...
