    I note that pci_enable_device() needs to be executed __before__
    the IRQ is obtained on 2.6.10, otherwise you get the wrong IRQ
    (IRQ10 on this system)B.

    This doesn't seem to be correct since the IRQ connection was set
    by the BIOS and certainly shouldn't be changed. On this system,
    interrupts that were not shared on 2.4.n and early 2.6.n end
    up being shared... See IRQ18 below.
