What method are you using to get your video card working? My advice would be to clone your hard disk with Carbon Copy Cloner to a USB hard disk and then make this bootable with Chameleon. You can then try 10.6.8 on the USB hard disk and check it works OK. This is the method I use and it has saved my skin many times!!!
I used *your* method with the GFX strings. Actually I'm using my 8800GTS now because when I boot in past the silver screen, the screen turns black and is shifted like 60% to the left.
And I will definitely try to do that.
Cloned, installed 10.6.8 on cloned drive. Upon first boot I got a KP but it was because of SleepEnabler.kext. Removed it, rebooted (and used pmVersion=0) and it worked fine, so now I'm installing on primary drive!
Successfully installed on main hard drive! Thought it was gonna be a really long and painful process but that was so easy. Thank God. Anyway, I can now boot into my GTS 250, but still no HDMI output. Eh... I bought a DVI to HDMI adapter so it shouldn't be too much of a problem... hopefully.
