You can tell the keyring daemon not to provide ssh-agent services.
Perhaps doing that and using the ssh-agent from openssh (which I
believe is still started automatically if no agent is running

To disable ssh services in gnome-keyring-daemon:

gconftool-2 --set -t bool /apps/gnome-keyring/daemon-components/ssh false

Some very thin documentation on gnome-keyring-daemon's ssh handling is
at: http://live.gnome.org/GnomeKeyring/Ssh

Again, thanks for the effort, but NO-GO!

I tried changing the setting for that boolean to false, both with
gconftool-2 and with the GUI gconf-editor, and also by running
gconftool-2 as root.  No change, nada, zip!  Log out, log back in,
reboot, ..., no change at all.  Unsetting the environment variable
for SSH_ASKPASS (edited /etc/profile.d/gnome-ssh-askpass.sh so that
the variable never gets set) changes nothing.  The only thing that
has an effect is unsetting SSH_AUTH_SOCK, and doing that means that
the passphrase is required _every_time_.

If SSH_AUTH_SOCK is unset or the socket is not present, ssh-add
fails with "Could not open a connection to your authentication agent."
Looks like the only options are (a) use gnome-keyring-daemon and
accept that the key is unlocked forever, or (b) use nothing and
enter the passphrase every time.

I am not sure where to modify it now days, but IIRC ssh-agent is started before your window manager is going in the xinitrc.
it used to be around line 62 of /etc/X11/xinit/xinitrc-common

My guess is the -t needs applied to THAT instance of ssh-agent.
