Correct. Note, it's likely that we have almost everything covered
already, so it's mostly testing (beyond implementing SMM entry/exit).
However, we have a large deployed base with no SMM support, so we need a
fallback if SMM is not available. It's also tricky to probe for working
SMM, I don't think there's a cpuid bit for that.
