The existing userspace-consumer regulator driver does provide some of 
the functionality I'm looking for (the on/off switch), and I think would 
be pretty easy to extend to provide the rest of it as well.  When I 
previously proposed using it as such though, Mark stated quite firmly 
that that wasn't going to fly [0]; this approach was my attempt at 
implementing a generic, abstracted mechanism as he had suggested later 
in that thread, though I haven't gotten any further feedback from him on 
what he thought of it.

If he's had a change of heart and would be open to the 
userspace-consumer driver taking on a bit of new functionality I'd be 
happy to go that route though.
