Signed modules is in, though, right?  And the fact that we have
CONFIG_SIGNED_PE_FILE_VERIFICATION means we're doing unatural file
signatures w/o using ELF, which I thought was the basis of Linus's
accusation that Red Hat was performing intimate/physical acts with
Microsoft.  :-)

I would have thought those were the nasty bits to get in; out of
curiosity, what's still missing?
