Ok, following up on this, I dropped in a new video card this weekend
(generic Radeon 7000), and my system crashes have gone away. So the
video card was indeed the culprit, must have been locking the PCI bus
or something.
Now I can leave mplayer looping overnight or run folding@home without
any problems. However...
With the latest rawhide kernels, I still can't run azureus for very
long. Not a crash, but the OOM killer seems to take it (and other
things) out abnormally early. The thing is, it happens in situations
where, near as I can tell, I'm not that low on memory. I do have only
256 MB RAM, and the kernel slab debug is using a lot of memory as I
documented in an earlier post to fedora-devel-list, but it seems like
the swap (and I've got 512 MB of it) has hardly been touched when this
happens. I am running with vm.swappiness=0, but that's supposed to
just keep it from swapping until it *has* to, not stop swapping
altogether (and it isn't).
Actually, I just had the OOM killer take out firefox while I was
bugzilla'ing something else :( Here's what it has to say for itself.
This is under kernel-2.6.10-1.1141_FC4(.i686):

Yeah, the OOM is "a bit" rash and stupid. I had a pc which i sent a 25
pages pdf (or was it ps) document to the printer - which was controlled
by gimp-print.
Needless to say, the system ran out of its 128 MB's of RAM in about 2
secounds, trashing the harddrive for about 10 minutes, killing off about
*everything* (including gnome dock etc.) - *EXEPT* the wild goose gs
(ghostscrip) prosess eating 100 MB's of RAM and 500 MB's of swap.
I eventually resorted to the power-cutting method of killing the
process...
When speaking of videocards and instability - i had a Vodoo PCI card
which had the bad habbit of suddenly resetting itself without warning. I
cant forget the first time it happened - i was showing some techy Linux
for about the first time. I was really, really impressed, and i was just
coming around to "stability". Then it happened. The monitor (i have 10
kg's of glass and vacum sitting on my desktop, its a shame the vacum
dosn't lift the monitor more...) made a *click*, and went to black with
rolling stripes on the screen. I thing about the only open app was
evolution...
The pc didn't actually *crash* - it just locked up the PCI bus or
something. At least it seemed like it was probing for HW all the time -
the floppy/cdrom blinked (just as it does when inserting a usb mass
storage device, and hotplug loads the mass storage driver) constantly -
and the switch told a tale of loosing the network connection every 10
secounds... Anyway, i was able to ssh in, and restart the machine.
this was during fc1, i.e. the Linux 2.4 days.
