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
vgapci0: <VGA-compatible display> mem

sc0: <System console> failed to probe on isa0

atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 on isa0
vt0: not probed (disabled)
isa_probe_children: probing PnP devices

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

pcib1@pci0:0:1:0:	class=0x060400 card=0x00000000 chip=0x25718086
rev=0x02 hdr=0x01
    vendor     = 'Intel Corporation'
    device     = '82865G/PE/P, 82848P PCI-to-AGP Bridge'
    class      = bridge
    subclass   = PCI-PCI
isab0@pci0:0:31:0:	class=0x060100 card=0x00000000 chip=0x24d08086
rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82801EB/ER (ICH5/ICH5R) LPC Interface Bridge'
    class      = bridge
    subclass   = PCI-ISA
vgapci0@pci0:1:0:0:	class=0x030000 card=0x2034107d chip=0x022010de
rev=0xa1 hdr=0x00
    vendor     = 'Nvidia Corp'
    class      = display
    subclass   = VGA

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
syscons.

Morgan
