Yes! That was (almost) it. Since there were constants defined for them
in the sshd source, I had thought that all the keys in standard-named
files were in a default table in the program, and would be
automatically loaded, but it turns out that I needed to add a "HostKey
/etc/ssh_host_dsa_key" line to my sshd.conf. Now everything is working
properly.

Thanks!
