8800 GTX problem

[samus_aran]

hi! i have an XFX 8800 GTX XXX and i've iDeneb 10.5.5

the video card DIDN'T work with NVkush and NVinjector (black screen after a loooong boot). i've tried EFI Studio with the 9f23 installer. but maybe I didn't do the right steps.

the video card only works (no black screen) if before one boot, i boot with -s and type:

mount -uw /
cd /System/Library/Extensions
rm -rf GeForce.kext
rm -rf NVDaresman.kext
rm -rf NVDANV50Hal.kext
rm -rf NVinject.kext
reboot

after this, the video card will be ok, but without any hardware acceleration.

one last thing: when i've installed the video card with efistudio, installed the 9f23 pack, and edited the files NVdaresman, NVdanv50hal and nvinject, the boot was really fast (less 1 minute) when the normal boot without video driver takes around 5-6 minutes!

please help meeee!
