    Here's an extract of the important parts.  What I don't understand here
    is that I do not see the PCI interrupt from XL0 being routed at all.

    XL0 is on slot 0, intpin A of pci bridge #2 (pcib2).

    The PCI bridge responsible (pcib2) is routing slot 1 intpin A to IRQ3.
    It's doing it twice, in fact.  I do not see where the PCI bridge is
    routing slot 0 intpin A anywhere.  If it isn't saying anything because
    intpin A is the same for both slot 0 and slot 1, then at the very least
    it should tell the higher levels that XL0 is on IRQ 3, not IRQ 11.

    The XL device thinks it is being routed to IRQ 11.   But it obviously
    is being routed to IRQ 3, presumably because slot 1 of pci bridge #2
    got routed first, and was sent to IRQ 3.  slot 1 looks like it is 
    device cbb0 (pci-cardbus bridge).

    If my analysis is correct, XL0 has no choice but to be routed to IRQ 3
    because of the earlier routing of CBB0 (also on intpin A) to IRQ 3,
    but the system doesn't see that.
