The error message on the Cisco side of things looks like:

Is there a safe way to make this work?

I'd imagine that you can use ssh-keygen to generate a replacement RSA1 or RSA2 host key rather than a DSA key:

  /usr/bin/ssh-keygen -t rsa1 -b 1024 -f /etc/ssh/ssh_host_key -N ''

...or "-t rsa" for a protocol-2 RSA key, if the Cisco can deal with those.
