I don't know, but what I do know is that there's a huge amount of
machines out there having these chipsets.

I would suspect there could be other uses - for instance, I don't think
having the microcode update code in Xen is the right thing, it could
easily live in Dom0 (which would also cause less work merging back
updates from Linux into Xen) if that had a way of bringing all physical
CPUs to a known state.
