Hmm... perhaps I'm experiencing something related to this?

I've recently made a fresh install of my system from 4.8-RELEASE and upgraded 
to -STABLE. Installed XF4 from ports etc. And I've got a MGA 450 as well 
(running singleheaded). Since then, sometimes I've had some strange 
hard-hangs too.

case 1) printing to a HP 1200 Laserjet via lpr and parallelport. Going dead 
slow when there's lot of graphics to be printed. Resetting the printer 
(couldn't find the jobs with kde's printer-job-app) would send the cpu-load 
to 100% and then everything would run deadslow on the desktop (running kde 
3.1.4). If I then try to change to console (ctrl+alt+Fx) the computer would 
hang and I was forced to make a hard reset/restart.

case 2) yesterday I played with xmame and tried it in 16-bit modes with no 
modelines i XF86Config. X started up just nice, but in a really high 
resolution. I then tried to change the resolution to something smaller (ctrl
+alt+-). Black screen and the computer hangs.

I've no clue what's up.
