You're not supposed to play with the microcode files. If you do and
something breaks, you get to keep the pieces.

If the official microcode files have a problem, then I'm all ears.
Anything else contrived which doesn't actually happen unless someone
manipulates them is not an issue the microcode loader should protect
against.
