Can get extremely messy wrt unload-related races. If you limit yourself
to uniform kernel<->module API - maybe. struct Dev would be natural candidate,
but #<letter> convention might get uncomfortable very soon and AFAICS you will
need to work on locking and proper refcounting - from the fast look through
code it's not a lot to change, but I didn't dig deep enough to say for sure.
The question being, is it really worth the trouble?
PS: apologies for delay with port of patch to current tree - it had been
quite a week, what with 2.5 fork and beginning of merges...
