I have a machine which changes RSA key every boot (boot from read only USB key).
The messages you are trying to avoid go away withi this in ssh_config:

  Host myhostname
    StrictHostKeyChecking no
    UserKnownHostsFile=/dev/null

you should have localhost instead of myhostname.

(are you really worried about someone hijacking localhost?) :-)
