Thanks! Alas, it does not, but having applied the patch does rule out one
possibility. If you are able to, compiling with --enable-debug with valgrind
installed and then running X under valgrind would be very, very useful. You
will notice a small hit due to valgrind, possibly a large one, but it will help
find the cause. To run X under valgrind often requires avoiding the suid
wrappers and you will need to remember to specify a
--log-file=/var/log/Xorg.valgrind for valgrind.
