Not that I am aware of. Don't know why you need it, but:
You can add an extra item to your boot.ini menu, which will allow it to boot to save mode. If you add a timeout of 1 or 2sec then they will be able to either move on to normal mode or change it to save mode. So they don't press F8 anymore, but just select it, and since there are only 2 options there are not able to select the wrong save mode.
