Personally, I think it's a great idea, if only because I stared long and hard
at the code once upon a time trying to figure out what is really OF-related
and what isn't.  It's somewhat clearer now that drivers/of has been factored
out (although, shouldn't it be drivers/dt???)

That said, it *is* alot of code churn.  If it's going to be done, I think it should be
done in concert with fixing a bunch of the function names which don't really follow any
sane naming convention, so that the backporting discontinuity only happens once.
