I know that ssh.com's version of sshd2 supports fall back mode to ssh1,
though fallback mode opens up the same security problems as sshd1 has.

Openssh may not help you with your keys problem, but it does support
fallback mode (I'm using it now with Teraterm) and it's incarnation of
ssh1 is not susceptible to the security problems of late.
