I haven't

I use keychain for this.

I have two aliases in my .bashrc

alias k="eval \`keychain --eval ~/.ssh/my-key\`"
alias kk="source ~/.keychain/\$HOSTNAME-sh && kill \$SSH_AGENT_PID"

so I just type 'k' to add authentication to a xterm/terminal/shell and
then kk to "de-authenticate". Best part is that unlike my old
ssh-agent approach (did make it part of the gdm session) is that it
transfers between xterms and sessions.  I used to even get all
technical and change the color of the background of authenticated
shells vs non-authenticated via extra magic in the alias but it was
causing issues over ssh.  Hrm, one day I will get back to fiddling
with it again.
