   MMIO isn't as bad as PIO, and the 'runtime choice' setup implies
   slowing down the MMIO path, too.

No end user will see the change then, no distribution vendor worth
their salt will ship with MMIO enabled.

Right now we get only PIO and everybody suffers.  Runtime MMIO
selection is a net win for everyone.
