Hi Frank,

My pc (AOpen AX4PE MAX motherboard, P4 3.06HT processor) doesn't
boot with -current, panics at mpacpi_attach_hook(), with or without
MPACPI_SCANPCI.

The ACPI namespace has _PRT for pci0 and pci2, not pci1.

pci0 (bus#0)
 -ppb0
  - pci1 (bus#1)
 -ppb1
  - pci2 (bus#2)

and kernel panics at ppb0 attach.

Attached is my workaround patch and full healthy boot dmesg.
If the patch is correct, mpbios.c also needs fixed.
