Obviously the card doesn't function as expected, but the BIOS might be
responsible too.

I'd try two things:  first, GENERIC, to see if when the card doesn't
attach at pci, it still does at isa (so GENERIC, or a kernel with
vga0 at isa?).  The other thing I'd check is the content of the PCI
configuration space for that device after a failed boot.  Precisely,
the content of the command status register for the flags IO_ENABLE and
MEM_ENABLE.

That way we could know if attachments is failing in vga_pci_match or
in vga_common_probe.
