    That's exactly how my code works.

    Found that out when I tested binding the agpgart driver.

    Ok, I guess that makes sense. My interface was primarily for special
    cases anyway. What does need to be done is a user level program that
    finds and loads the proper modules automatically. Maybe we could use
    the existing hotplug scripts or we could even start from scratch. Maybe
    we should make a file in the source tree where driver developers can
    list their supported hardware IDs but more importantly documentation on
    the attributes registered into driverfs.

    great!
