Unfortunately, you'll end up with the software 3D driver if you have acceleration disabled.
I have added the full output while 3D accel is enabled, hope this helps.
You'll have to find out what debian uses on wheezy (r300c vs. r300g).
I can't tell... maybe Jonathan can shed some light here :-)
However, if you still get hangs even without using 3D, there seems to be a problem with acceleration in general on his system.
Curious is that system runs stable (no hangs nor crashes) in gnome fallback mode as soon as "firmware-linux-nonfree" package is removed as stated in #c1.
So what we have now is that system does not crash if:
1/ "firmware-linux-nonfree" package is not installed, or 2/ Option "NoAccel" "True" is set at xorg.conf
