That is true. I would guess that the people who would bother checking
would probably be able to figure it out. In the interest of correctness,
the message could say
 
        If you have access to '192.168.0.123' and it runs OpenSSH, you
        may be able to run ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key
        on it to verify this key fingerprint.

However it might be phrased, even the clue that ssh-keygen -l -f is a
likely way to check would be extremely helpful.
