Sorry, but in /etc/X11/xinit/Xsession I find that SSH_AGENT is not used
with Gnome:

     case "$1" in
         failsafe)
             exec -l $SHELL -c "xterm -geometry 80x24-0-0"
             ;;
         gnome|gnome-session)
             # lack of SSH_AGENT is intentional, see #441123.  though
             # the whole thing should really happen in xinitrc.d anyway.
             exec -l $SHELL -c gnome-session
             exec /bin/sh -c "exec -l $SHELL -c \"gnome-session\""
             ;;
         kde|kde1|kde2)
             exec $SSH_AGENT /bin/sh -c "exec -l $SHELL -c \"startkde\""
             ;;
     ...
