- On amd64, just assume type #1 is always used. PCI 2.0 mandated deprecated type #2 and required type #1 for all future bridges which was well before amd64 existed. - For i386, ignore whatever value was in 0xcf8 before testing for type #1 and instead rely on the other tests to determine if type #1 works. Some newer machines leave garbage in 0xcf8 during boot and as a result the kernel doesn't find PCI at all (which greatly confuses ACPI which expects PCI to exist when PCI busses are in the namespace).
