Thanks for your answer Mike. The system is actually an old Celeron on an
Intel i865 based mainboard so the hardware should be pretty well
supported I guess and after all - it did work with 7.0. The machine is
only used as a router so the lack of virtual terminals aren't critical
but I still would like to solve it. I will have the owner look for a
more recent BIOS and then I'll reinstall the GENERIC kernel before
filing a bug report. Here's a more verbose dmesg snippet that might give
someone a clue:

agp0: <Intel 82865 host to AGP bridge> on hostb0
agp0: allocating GATT for aperture of size 128M

isa_probe_children: probing PnP devices

What is that vt0 (disabled)? Is that related? pciconf reports this:

Googling on this turns up a lot of older posts with references to PnP
incompatibilities and ATA but I can't find any info that helps me with
