This driver doesn't really do very much of anything as things stand, so
I don't see really see all that much value in picking it up right now,
since the non-coherent bits aren't usable yet.

I don't think this should have a default set w/ the support that this
patch brings in. Perhaps later we should be doing defaulting, but not at
this point in the series.
Other than that, this is fine by me:
