Ah, ok. It would be most helpful if you could add a bunch of printf's
to the attach routine in sys/dev/acpica/acpi_pcib_pci.c to see where
the error comes from.
Oh, I think I've seen this before. This is due to incompetent BIOS
writers. Edit sys/dev/acpica/acpi_pcib.c and in the acpi_pcib_attach()
function comment out the acpi_DeviceIsPresent() check. The BIOS is
claiming that the specific PCI bus doesn't exist.
