But you need to run X to trigger it. That pretty much has to be
either an X11 or hardware bug

(Seeing if it answers network traffic is a good bet)

Well yes, I agree with your opinion about the KDE desktop (ok that was cheap)

When you say "screwed up" how do you mean

Ok. That froze

That does all sound like hardware or X or combination problems rather
than Linux.

Some suggestions to help pin it down:

o If you have a spare video card or one you can swap with another
box then swap it and see what occurs
o Leave the box contiually doing things for 2 or 3 days and see it
it dies - the rc5 cracking client will let you do something 'useful' ;) as that. THis will keep the CPU warm..
o Run badblocks over all your disks. I doubt very much you are seeing
a disk crash caused by a badblock thats either deep in your swap
or in something like an X font file but it pays to check
o If you have RH 5.0 handy run metroX instead of XFree and see what
happens. Just that varying the X server may give clues
