It has also worked against, well, me in the past in that I couldn't
figure out why a driver simply didn't want to work with memio while
it worked perfectly with pio. Then I spotted the bus_pio.h header at
the top and cursed, cursed, cursed.

I'm all for performance tuning, but the newbus optimization is just
too weird for its own good this way.
