Could you get a better backtrace with gdb after installing xserver-xorg-video-ati-dbg?
You might need help from http://wiki.debian.org/XStrikeForce/XserverDebugging

Did you try some earlier snapshots of xserver-xorg-video-ati on this device?
We had plenty of snapshots between 6.7.197 and 6.8.0 in experimental,
they are available through snapshot.debian.net.

By the way, your xorg.conf is a big mess with lots of non-trivial
options. Make sure you get the same crash when using no xorg.conf
at all (or with a single device section and no option).

And please send the whole Xorg.0.log from the crash (the one
with vesa has been attached by reportbug but it's useless)
