EVGA 8800 GTS + 9742 = freeze
OK, bought a EVGA 8800 GTS, because they're supported in the latest beta driver, 9742. But as soon as X launches, the machine freezes completely, not even SysRq works. I don't know what info I can provide to help. Tried kernel 2.6.16 and 2.6.18, with and without the compiz options (from your howto). I'm really disappointed. To add insult to injury, the opensource nv driver doesn't work either, although that's not your fault, of course.
Attached are the log of one the the crashes, which ends randomly and most likely isn't complete (I can't even flush the filesystem because SysRq is dead), and my current xorg.conf (I know it's a mess but it has been working). I have an Asus K8N4-E Deluxe motherboard with an AMD Athlon64 3200+, and a Viewsonic VX2025wm. Everything works perfectly in windows xp. If you need anything else, just ask.
