For this sort of case it seems like it would be much cleaner to have
some sort of proxy device that would load the module upon open -- so the
also drivers would end up creating both alsa entries in /dev, and also
proxy entries for the supported oss devices.

That way, you could have the explicit device entry (which I think is all
around saner), but not the overhead of rarely used modules.

In New York, most people don't have cars, so if you want to kill a person, you
have to take the subway to their house. And sometimes on the way, the train
is delayed and you get impatient, so you have to kill someone on the subway.
