I'm shocked, X crashing...
In the Xorg.0.log file there will a rudimentary backtrace (no symbols),
but at least it will indicate which part of the call chain needs
investigation (driver vs extension vs core). However, to get any useful
information out we need to attach gdb. This can be done either by
attaching gdb to X one it is running or by generating a corefile upon
crash (with X -core and appropriate ulimits). To attach gdb post-mortem,
use gdb X $corefile . Once you have the crash inside gdb, type 'bt full'
and send the stacktrace to the guilty parties and xorg-dev at lists.x.org.
