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.
