The problem here is that the PCI bus probe is returning a corrupted PCI
Vendor ID. Querying the PCI config registers after the system has
started shows the correct Vendor ID, but the kernel seems to 'lose' the
2nd nibble of byte 0, turning 0x18 into 0x10:
This is from the problem PC booted with a 64-bit kernel:
