I have to say that I share Lars' concerns with this one, especially for
the set function (which doesn't quite gel with the description above) -
it may be that this really is the best solution for the problem but it's
not entirely clear what the problem is and like Lars says there's some
other stuff in play here.  If there's something that the core just isn't
doing that any driver trying to do similar things is going to want we
should fix the core instead of requring drivers to do work.
