Would it be ambiguous if a false keyid appeared in the unhashed section?
If one did appear, but was fake, do you say the signature is actually bad
when the hash corresponds (first two octets), and matches another key on
your ring?

Well unless you check every public key in the users keyring you would
never know if another key would verify the signature or not. Since it is
doubtful that anyone is going to do this in their implementations I would
have to say if it has a fake keyID in the sig the sig is to be considered
invalid.
