One thing I did > confirm in my case is that it happened either with or without X running. Total lockups are very difficult to diagnose - you probably have to log the console via a serial connection to another machine, or setup a net dump, and even then you may not get anything useful. My case has more debugging potential, it always occurs during a particular screen saver, and you can log in remotely to the machine, so it definitely an X related problem, though so far I have had to reboot the machine to get the keyboard/mouse/display to respond.
