I decided to upgrade to the newest (as of earlier today) DRI tree, along
with 2.4.3-ac5.  I was playing Quake3 again, and got a lockup which has
never happened before: the monitor on my Radeon went blank, but Quake3
kept going (I could hear the sounds and still "t"alk and hear the
transmission).  Usually the sound will loop over and over and sysrq will
either work or not work.  This time everything worked except for the
monitor, but it locked up as soon as I quit the game (blindly).

I set up a serial console on another box and ssh'd in to a screen'd
minicom process on my second head while playing Q3 on the first.  During
play, no messages occurred.  After about 20 minutes, the older style
lockup occurred (monitor went blank, sound looped, sysrq works), and as
this happened, no messages appeared on the second head.  Upon reboot,
minicom had captured this looping output:

SysRq: Resetting

So, there now seem to be three different kind of lockups.  Totally dead,
somewhat dead (sysrq works), and only partially dead (only the Radeon
head goes blank).  Fun fun. :)
