This is from a Toshiba Portege 7010CT:

[root@portege ~]# dmesg -s 1000000 | grep PIIX4
PCI quirk: region fe00-fe3f claimed by PIIX4 ACPI
PCI quirk: region fe60-fe7f claimed by PIIX4 SMB
PIIX4 devres B PIO at 006d-0070
PIIX4 devres I PIO at 038c-038f
PIIX4 devres J PIO at 0530-053f
PIIX4: IDE controller at PCI slot 0000:00:05.1
PIIX4: chipset revision 1
PIIX4: not 100% native mode: will probe irqs later
