Then why do we need to test a bunch of machines? If we're just using
CPUID (which we check for before using), it's no problem. It's just
the "enable SSE" part that needs privileged instructions, and that's
probably not much of an issue for you, esp. since we prefer CWSDPMI
anyways, which supports it.
