Hi Keith!
  I'm sorry but I didn't try it with a regular text console. My card BIOS knows
only 80xN video modes, which are unacceptable for me. I'm operating intelfb on
1600x1200x32 as well as X. Of course I can try to boot just in pure text, but
only for a limited time, otherwise I would go bananas :-).
  The crash is obviously so "definitive" that nothing can be logged. For 
example, when a sound is played, it immediately starts to loop the last DMA
buffer. Sometimes the UPS indicates a substantial increase of power consumption
(like when compiling on both cores), but sometimes not. Strange.
  I've made a photo snapshot of what is visible on the screen. It's on

  The pattern obviously changes a lot of times for about a second and then
stops like shown.
