I managed to find some time this morning. It happened after exiting 
MythTV Live TV for the third time. After that attempting to enter MythTV 
Live TV would fail with a blue screen where the video should be and X 
would use 100% of the CPU.

The messages.gz contains the agp and drm lines from /var/log/messages. 
Xorg.0.log.1.gz is after exiting Live TV for the third time and getting 
the 1/2 black and 1/2 blue screen. Xorg.0.log.2.gz is after reentering 
Live TV and getting the blue screen.

Let me know if you need more information.
