Ah, very nice, I've wanted this for a while now, it would make a number
of different drivers much smaller and simpler to add new device ids to
(no multiple lists of ids, one for the module loader and one for the
sub-driver that is in the single file.)

If this doesn't break any userspace tools, I have no objection to it at
all:
