Automatic locking off ssh agent

Hi there,

I'm trying to configure my screensaver to automatically lock my ssh-agent every time my screensaver kicks in, but it requires a password from the tty, which makes this unautomatable.

Is there a way it can be made to automatically use an encrypted password file instead?
