Perhaps someone who knows our PCI code better could address this?

Here is the valid case (without ACPI):
pci_open(1):    mode 1 addr port (0x0cf8) is 0x80003840
pci_open(1a):   mode1res=0x80000000 (0x80000000)
pci_cfgcheck:   device 0 [class=060000] [hdr=00] is there (id=700c1022)

Here is the invalid case (with ACPI):
acpi0: <AMD2P  AWRDACPI> on motherboard
pci_open(1):    mode 1 addr port (0x0cf8) is 0x80ff003c
pci_open(2):    mode 2 enable port (0x0cf8) is 0xff
panic: AcpiOsDerivePciId unable to initialize pci bus

Obviously, the pci_open(2) is bogus.  If no one else addresses this, I
will try to get to it soon.  For now, try changing the panic to a return 0
and see how it affects system operation.

Nope, just something I noticed.
