For what its worth, this hasn't been a problem on x86 at all.  All the 
"interesting" instructions are used via macros/inline functions, and 
there have been no instances (that I know of, at least) of naked ones 
appearing anywhere.  And all the gatekeeper maintainers are definitely 
aware of the paravirt constraints, so I don't think any would make it 
past review.
