secureboot patch in its current state has only one goal: make microsoft
sign existing image and load linux. If we integrate it with GRUB
signatures check (as far as GNU policy permits but rest would be tiny)
then it will be a matter of choosing which way xen is going to be
signed. I'd recommend GnuPG detached signature (xen and xen.sig) but
don't insist on it.
