The fix is what Jean mentioned. When gnome-power-manager starts suspend it sends a dbus message to gnome-screen-saver that the machine is now inactive. That kicks on the screen saver. During the resume a dbus message is sent that the system is now active and to disable the screen saver. If you tell gnome-screen-saver to lock the screen then it will ask for a password.
