    At the moment I'm struggling with the fact that the order of resumption
    of system devices appears significant (ie, I get hangs on resume with
    the stock kernel, but changing the list_for_each_entry in sysdev_resume
    to list_for_each_entry_reverse makes things work) but there doesn't seem
    to be any mechanism for providing proper ordering when there isn't a
    tree structure. This also crops up with resuming my wireless hardware -
    it tries to do a hotplug firmware load, but the IDE bus hasn't been
    woken up yet.

    Do we need a more fine-grained dependency structure than the current
