Like Jan said (ooooh, please use reply-to-all), the word "adapters"
is just too generic. We have lots of other kinds of "adapters".

So some driver(s) already uses /proc/adapters? That's too bad.

It really doesn't belong in /proc, but even if it did, would
/proc/speech make any sense? or /proc/synthesizer?
