I've been waiting for it to happen again so I can back up my report with
actual data, including /var/log/messages, /var/log/Xorg.*, dmesg output,
lsmod output etc. However the bug doesn't want to collaborate and is now
in hiding. I've turned off power-saving and the screen-saver, and it
hasn't happened again, which may be a clue in itself, but if you can
provide the above data, create the BZ entry and report it here so others
can add comments.
