So running a non-SMP kernel on a SMP machine is fine, but wct1xxp can't
run in an UP kernel on a SMP machine?

This is a very important thing to know because one would assume that as
the kernel is fine, loading the module should be OK too.

Does this restricion apply to any other zapata modules?

How about HT?
