:) I've got a Dell/Trinitron monitor, so it must just be more robust then
yours. fbset itself never caused the panic, it behaved fine. Mayhaps it's
an incompatibility between bash and the fb-driver?

I'm assuming that it crashes no matter what I switch back to, because of
the video mode...X or not, it doesn't like 1280x1024.

Mine doesn't go black, however it does seem to resync the videomode half
the time (monitor clicks and flickers like it's changing resolutions)
I figure it's the fb-driver then. And I'm not skilled enough to even
attempt to debug it. :) Anyone know if the 2.4 kernel tree behaves any
better?

Yep. That's what happens on mine too. Anyone know how to change the
default boot-up video mode? I tried playing with my yaboot additions
"video=aty128fb:vmode=24:cmode=32" but nothing I changed made any
difference.
Thanks in advance...
