I like how minimal this looks, though it does worry me that is a little
too easy... (Not least the question why the simulator doesn't work with
forcewake... Doesn't that strike you as odd that we have rc6 bugs and
the simulator dies... ;-)

I think I would rather see this as an intel_info so that it can be
expanded upon simply for future/past simulators.

However, the fundamental question is do we ever ship simulators? If we
try to avoid carrying pre-production w/a, shouldn't that mean that we
don't even contemplate pushing simulator interfaces.

Having said, carrying these patches centrally does mean that will be
reviewed and kept in mind for future iterations.
