    I have an irq problem with yenta on an nec versa sx. Seems it always wants
    to use an irq that is currently *IN* use. irq 3/4 aren't allocated by a pci
    device. (3 is free, 4 isn't)

    slot 0 always grabs irq 10 (video according to lspci), and slot 1 always
    grabs 5 (sound)

    If I have a cardbus card in slot 1 (top slot), it and my sound card will be
    on the same irq which causes problems.

    I just don't understand why they don't make laptops that can go above irq 15
    (PCI only). Maybe windoze can't handle it.
