This is not actually what the patchset implements.  All it's done here
is using PE files as envelopes for keys.  The usage this enables is to
allow for whoever makes a module (binary only or merely out of tree for
whatever reason) to sign it and vouch for it themselves.  That could
include, for example, a systemtap module.
