I think I got the same crash issue.
Driver 290.10 is very stable, starting with 295.20 I experienced a lot of crashes.
Infact 295.20 was worst, 295.33/.40 improved the situation and 302.07 almost looks stable but I still encounter a crash.
I assume one is able to trigger the crash pretty constantly by browsing using Chrome and trying to "scroll" or "resize" the window.
nVidia GeForce 8600GT
Driver 295.20 up to 302.07
OpenSUSE 12.1 32-bit
TwinView / Dual-Screen Setup
Snip from my Xorg log which contained the crashes:
[ 1111.811] 0: /usr/bin/Xorg (xorg_backtrace+0x37) [0x80a86b7]
[ 1111.811] 1: /usr/bin/Xorg (0x8048000+0x64a0a) [0x80aca0a]

Fatal server error:

Since my system restarts Xorg again, the actual crasher Xorg.log is not directly embeded in the nvidia-bug-report.log. Attached it aswell.
If anything else needs to be dumped or provided please ask.
It appears 295.20 is much faster including the latest 302 series (yeah, xrandr!!!) which I'd really like to start using in production finally if it doesn't crash. Until then it's down to 290.10...
Mind that the 7z.gz bug report is actually a 7z compressed file, needed to rename and recompress it appropriately to get it to upload here due to the size.
