See my reply to Avi: all offsets of an portio region must be the same.
Said Avi doesn't understand. VGA for example has many ports.
Or are you saying, split the input into sets of discontinuous ports,
within each set you can use only one offset?
They should actually only differ in access width, but there is still at
least one counter example (of course IDE...). Given that this is just a
portability helper, all this will likely be reviewed and cleaned up when
getting rid of old portio.
