By the way, as far as I know, FreeBSD already runs on machines with a
non-power-of-two number of cores:

 - The AMD Opteron architecture supports an arbitrary number of cores in
   a HyperTransport ring; there are triple-socket Opteron motherboards,
   and AMD is expected to launch a triple-core Phenom this quarter.

 - The Sun UltraSPARC T1 (which runs FreeBSD/sun4v) is available with
   four, six and eight physical cores, each with four concurrent
   execution threads, giving a total of sixteen, twenty-four or
   thirty-two logical cores.

We also have run extensively on sparc e4500 systems with random numbers of CPUs like 10, 12, and 14.
