Yeah - sorry about that - the fact that cpuid is needed so early makes
it painful to cache the results.  Also, cpuid isn't really called
frequently, so I don't think there's much harm in doing explicit
detection.  Now that I think about it, though, it's probably better to
keep the name cpuid() and rename the low-level cpuid to __cpuid().
