I'd rather see it stay as-is, until all ports adopt the noncontig model,
whether they need it or not. contig is just noncontig with one segment,
and the inconsistency is bad, I think. We should just adopt the new
model everywhere and be done with it.
When I get back from Pittsburgh, I plan on doing the necessary goo to
the hp300 pmap.
