Too bad we can't just clean up all the open-coded mmio accesses as well. It shouldn't
be hard, but some platforms are full of them, and there is definitely some regression
potential.

Yeah :-/

I'm poking the IXP4 people a bit, it seems to have a large hobbyist
following due to all the NSLU2 hackers out there so lets see if someone
picks up the challenge to go and clean up this stuff.
