I was thinking of a separate effort, maybe teaming with a hardware security
  house, e.g. RSA.  I was actually thinking more like a smart card-like
  system, where the card actually stores the user creds, contains its own,
  and the kernel verifies that it is what it says it is (so you can't just
  pop out the card or splice in and pretend to be it) and they verify user
  creds without the actual user creds (e.g. password) ever actually going
  over the wire or into the kernel (save where the user types it in, and
  it immediately gets converted into something else in a one-way process).

Indeed.  We should make the kernel as secure as possible.  The only entity
  that should not trust the kernel should be the smart card, and the kernel
  shouldn't trust that it hasn't been swapped; it should check.  :)

I'm interested, although my knowledge and time are always very limited.
