And if you don't use such a system, then how do you deal with future versions of the software that will allow the user to swap DH keys from underneath the ElGamal keys?
[Stupid typo my part. This was supposed to be "swap ElGamal keys from under the DSA keys."]
Interesting question even if you are using separate signature keys. You've got a new signature key. You want to bind your recovered EG keys to it. So I guess you just strip the self-certificates from the EG keys, and add new ones made by the new signature key. You can still decrypt messages, and even pgp5.0 would be able to cope with that (it'll try to fetch keys to check the certification on the signature key).
