I think the ia64 ordering for 'io and mem' is probably more correct
(alphabetically sorted), so I would fix i386 and amd64 and leave ia64 alone.

The powerpc 'machine' changes are wrong I think as it would break GENERIC64
and powerpc64 kernel configs in general.  Nathan purposefully removed
'machine' from the powerpc DEFAULTS.
