    We -can- support multifunction cards such and these, and no we don't
    need to hack the infrastructure to do it. You might need to hack the
    subsystem drivers a bit to make them more flexible, but that's it.

    WRT the specific example of joystick ports, it is already possible for a
    sound driver to register a joystick port. No problem there either.
