These are simply implemented as emul.freebsd.kern.smp.cpus etc. See
how this is done for linux. Yes, there is no support for amd64 binaries,
but it is pretty easy to add. It is more work to get all the new syscalls
in place. As I mentioned before, if someone can give me a set of binaries
and libraries, I can take a whack at it.
