--- Comment #1 from Damien Miller <djm at mindrot.org> ---
Right, we don't support DSA keys with q!=160 because the SSH protocol
isn't specified for them. We also refuse to generate DSA keys with bit
lengths other than 1024 for this reason. Are you generating your keys
using openssl directly?

Changing this will require a protocol extension and the keys used will
be called something other than "ssh-dss". I'm not sure whether it is
worth it, since we support ECDSA modes that are faster and more secure.
