That's a very good point. It's important to have a secure login path. This is an especially important issue in a shared computer lab, where people can log into any machine they like.

It would be nice if gnome or KDE could be configured to request an "uninterceptable" keystroke combination before allowing you to log in through gdm or xdm. I don't know enough about X input handling to know how feasible this would be.
