The question is what does "malware that circuments Secure Boot" mean?
Does starting up a hacked KVM and running Windows 8 under KVM so that
malare can be injected count as circumenting Secure Boot?  If so, will
you have to disable KVM, too?

What if someone implements a virtualization bootkit for Windows 8.
Will they revoke their own key?  Somehow, I doubt that....
