How often do new drivers get added to media state trackers (real question)? It
seems like the kind of thing that doesn't happen all that often and good review
should catch.

That seems... ugly. And it builds more than we need to since we wouldn't
actually end up installing the state tracker. It would also confuse the heck out
of me if I had turned OMX on and then didn't get an OMX driver or an error.

I have some patches built on top of this that do that grouping, as well as some
other cleanups that I'm pretty happy with the result of for handling linking
drivers into state trackers.
