I thought it was OK for payloads to run over coreboot.  We don't load them
until we're done.  Right?  What am I missing?

Shouldn't this cause problems with the way we write mptables?  If the
mptable is too big this would write it over our stack, then zero it back
out.  My pending patch corrects this, but I didn't know it was an issue.
