Petr,

Thanks for the response!  I've tried a number of the suggestions...my
comments are inline.

It's an AthlonXP VIA Chipset of some sort (KT266 maybe?), but I think
your point is a good one, and I actually DO have a PCI videocard to try,
so I'll give that a shot and report the results.

I will run this test and see what the results are...this is a great tip
for figuring the crash problem!

I've tried fbtv + aty128fb drivers, but I'll try the VESA fb drivers
too, see if it's really the video card drivers, but I think your above
suggestions are more likely to succeed.

Thanks for your help!
