Meh, needs parens around the 'bhyve_cpuid_base | CPUID_BHYVE_FEATURES',
which somehow I didn't see in the first build.

I shall persist in *trying* to get a Bhyve setup which actually manages
to boot a guest (or failing that, getting someone to boot it for me
since Bhyve clearly hates me) before sending v4 with that fixed.
