    I don't think we can fully drop support for these systems.

    Did they have an unique PCI ID or something else that could be tested
    for?

    Perhaps it could be just a white list like dmi_year > 1995 to disable.

    Depending on how often floppies are still used this might save
    non trivial amounts of power on newer systems :)

    Anyways it would be probably good to convert this to the new infrastructure,
    and remove the old hooks, but the interrupt-context issue would
    need to be fixed first.
