Hmm... I don't see anywhere else in the kernel that uses both default and
select to express the same dependency.

Also it seems it will be really ugly to make this work if you make the CM and
DM options tristate (as they should be, since it seems if we're going to this
trouble we should support situations like building IPoIB into the kernel and
then building the CM and, say, SDP as modules).
