    Oh... the kernel pci-irq code looks for the "compatible router" if it
    is set; if unset, then it looks up the ID's of the router device.

    0x8086, 0x1234 is not a known router type, so the kernel decides it
    can't interpret the routing table.

    0x8086, 0x1234 is listed in pci_ids.h as an 82371MX. I'm suspicious
    of that: the MX chipset has an 82443MX, not an 82371. In any case, I
    think pci-irq.c should check both sets of ID's for a match.
