    I've been holding off on making many changes to PnP at the moment,
    because I have been considering replacing it with a new (more modern and
    ACPI capable) ISA/LPC bridge driver. This work would likely begin after
    my PCI bridge driver rewrite is finished and merged (as the PCI work is
    in some ways a prerequisite).

    Still, if there are changes to fix actual bugs, then I'm all for them.

    Also a few features could be added. Specifically PnPBIOS
    hotplug/docking station support. If anyone's interested, I may
    implement it (and it would use some functions that were removed by this
    patch). Furthermore, ISAPnP could be made a module. PnPBIOS probably
    couldn't.

    Correct.

    Not that I'm aware of.

    So in short, I'd rather not remove them, because they take away from the
    original design of the PnP layer.

    Thanks,
