I've been reading this thread with great interest, but I can't figure it out.
I install 10.6.3 with a 6970, and everything works fine, except the graphics get stuck at 1024*768 ('graphics card not supported' during boot).
I subsequently patch to 10.6.8, the system boots in what looks like 1920*1200. I get the Apple logo at 1024*768 (with the spinning wheel), the screen goes blank for a moment, then the full res blue screen comes up and it hangs there (sometimes with a working mouse pointer, sometimes without, haven't figured out when it does what).
At this point I'd settle for any sort of res, so if anyone can shed some light on this I'd be most grateful !
Thanks
Pete
