  On the other hand, I can think of no better way to force root logins to
be from a particular set of keyboard(s), perhaps with specific keymaps
loaded.
  Maybe passwd should complain once, but for root, let you continue anyway.

  Unless the attacker knows that the keyboard was in numlock mode, they still
have to brute force all 8 digit passwords.
