I had the same problem previously with 2.6.32-trunk; yesterday, I had it
also occur with 2.6.32-3. I haven't tried with the experimental 2.6.33.
The hard part of diagnosing is its randomness; my system was up for 9 days
before it occurred, for what it's worth.
I found that /var/log/kern.log gave a little more information than
/var/log/messages. Here's a log snippet from the time of my crash:

After ssh'ing in from another system, I noticed that xdm had crashed. I
tried restarting it, but was unsuccessful. The last lines of my
/var/log/Xorg.conf.0 were:
(II) AIGLX: enabled GLX_MESA_copy_sub_buffer
(II) AIGLX: enabled GLX_SGI_make_current_read
(II) AIGLX: enabled GLX_SGI_swap_control and GLX_MESA_swap_control

(II) GLX: Initialized DRI2 GL provider for screen 0
(II) intel(0): Setting screen physical size to 380 x 238
Fatal server error:

Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.
Please also check the log file at "/var/log/Xorg.0.log" for additional
information.

Hope that helps some,
