Just thinking out loud here, but this seems rather unlikely.  Implementing an
RSA library in the microcode would be an incredible amount of work and waste of
microcode space, and there wouldn't be any real advantage over just using a
MAC, given that the only way to get at the MAC key would require a nontrivial
amount of reverse-engineering effort.
