the video output is permanently broken until reboot (i was able to
gather logs by using delayed rc.d scripts).

ok, i've tried changing random BIOS settings, and found that changing
"AGP Aperture Size" from 128M to 64M solved the problem with the new
PCI bus driver. (i have a computer with 512MiB of RAM and an AGP video
card with 128MiB of RAM.) weird. any comments on that?
