    Waste of space having a busproc routine. The maintainer removed all the
    usable hotplug support from old IDE so this might as well be dropped.

    NAK. I think this fixup should be testing if the device port 0 is in
    native mode before doing the fixup. In comaptibility mode bar 0 is
    ignored and the correct compatibility values set up in the resource tree
    by the PCI layer as of 2.6.18-mm-mumble. They are also of course on a xx0

    "Close but no cookie": please fix the PCI quirk to match the current -mm
    behaviour with the ATA resource tree. Otherwise - nice driver.
