But it's not just parisc.  It's six other architectures as well, some
of which aren't even SMP.  Does !SMP && NUMA make any kind of sense?

I think really, this is just a giant horrible misunderstanding on the part
of the MM people.  There's no reason why an ARM chip with 16MB of memory
at 0 and 16MB of memory at 1GB should be saddled with all the NUMA gunk.
