The proposed patch can be seen in the branch linked (lp:~smoser/ubuntu/natty/openssh/lp-686607).
With the change applied, I get a message like: $ ssh jimbo @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed.

Add correct host key in /home/smoser/.ssh/known_hosts.uec to get rid of this message.
