    Strange. Your interrupt router is a bog-standard PIIX4, we know how to
    route the thing, AND your device shows up:

    Can you (you've probably done this before, but anyway) enable DEBUG in
    arch/i386/kernel/pci-i386.h? I wonder if the kernel for some strange
    reason doesn't find your router, even though "dump_pirq" obviously does..
    If there's something wrong with the checksumming for example..
