mesa   intel-2008-q4 branch  commit 154a9e5317f890618932cea0129ef887e16baf84
kernel  for-airlied branch  commit 66647dc60d16fae9f6963fd98b6d9baa1a8dac69
libdrm  master branch commit b0d93c74d884b40bd94469a5ef75fdb2fef17680

After enabled UXA, then run VT switch both with and without compiz enabled will cause the X and gnome-session being killed but the system still not hang. 

Reproduce steps: 
1. enable UXA by edit xorg.conf
2. xinit&
3. gnome-session&
4. chvt 1

You're missing a GM965 fix that was committed a week ago in the kernel and the dmesg attached to your bug report.

After rebuilding the kernel, it works well now.
