For my Dell Latitude D600 laptop, xorg-x11-drv-ati-6.8.0-2.fc9.i386 segfaults at startup. This leaves the laptop panel off; the only way I've found to get it to come back on is to reboot. I'm not completely sure, but I think 6.8.0-1 was ok; the crashing started with 6.8.0-2.
Created attachment 296532 [details] the crash log from /var/log/messages
Created attachment 296533 [details] output from lspci -v
Created attachment 296534 [details] Xorg.0.log from the crash
I can reproduce the crash both with and without /etc/X11/xorg.conf being present. (The files I attached above were with /etc/X11/xorg.conf *not* present; the X server autodetected everything.)
actually a server upgrade most likely broke things, but a new ati driver is in koji now.. should land in rawhide soon...
Looks like duplicate of bug 435382 to me. *** This bug has been marked as a duplicate of 435382 ***
