Hmm...I wonder what the difference is. My system is nearly identical
to yours -- PA-2011 (it's a VIA VP2, btw), 64 MB SDRAM, Matrox Millennium II,
K6/200 (instead of your 233), SoundBlaster AWE 64 Value (instead of your
SB 16), and 5.7G Maxtor IDE instead of your Quantum.

As are mine...
I'm beginning to think that you're right about this being a general
DMA problem. I just upgraded to XFree86 3.2.2.2 (from Debian slink),
and now using X will lead to an identical freeze after a minute or
two of use. This happens even if I don't enable DMA on /dev/hda.
The higher the resolution I use, the sooner the freeze occurs.
When it freezes, it's total -- nothing works, not even Alt-SysRq-* .
System doesn't respond to ping, either. Not pretty.
Interestingly enough, this freeze happens with both 2.0.33 and
2.1.10x kernels. I'm wondering if there's a DMA bug somewhere,
and both the new XFree86 and the 2.1.99+ kernels are tickling
it.
