    There is an additional catch with the resources to be careful of.
    Some environments require we register/unregister additional
    IRQ routing tables. Thats a minor problem but does affect things
    like IBM thinkpad 600 docking station. Thats a transparent
    bridge with devices that appear and vanish stuck behind it.
    Similar problems - it needs

    pci_attach_behind_bridge()
    pci_destroy_behind_bridge()

    functionality just like the cardbus toys
