I was wrong about the improved stacktrace, when I looked carefully at it I noticed that for some reason I'm getting symbols for some addresses in the DRI module but not all addresses. I find this a little bit strange. Anyway, I can also repro this bug using the 2.3.1 driver that bryce provided a test .deb for here: http://people.ubuntu.com/~bryce/Testing/intel/hardy-i386/xserver-xorg-video-intel_2.3.1-1ubuntu1_i386.deb Below is the backtrace (slightly different) that I'm getting with the new 2.3.1 version of the driver:
