Far as prover verification, these people mostly solved it:

They start with small logics you can do by hand in verified code. They gradually build on them, one layer at a time, increasingly sophisticated logics until they have a useful theorem prover in first-order logic. I also found a HOL-to-FOL converter. Since most of their stuff is HOL, that means we're almost done at that point for the verification chain.
