The ICH4 is a southbridge and contains many different PCI devices and
legacy devices including the PIC and the PIRQ routing hardware to map
the PIRQs to PIC int lines. As such it is not a good place to try and
draw inferences from as it has a lot of capabilities not included in a
normal PCI device.
