Just finished updating my AMD machine to 10.5.6, but I'm now having problems with the video driver.

I tried the EFIStudio string install but the machien gives me a blank screen (mouse freezes). Removed it using single user from com.apple.Boot.plist file and it loads fine though no nVidia driver installed. Tried the old NVinject.kext and the NVdarwin.kext but doesn't work as well.

Any help to point me in the right direction is appreciated.
