KDE/KDM starts a new X display with the new user, whereas (as far as I know) GNOME/GDM lets the new user take over the existing X display, which is supposedly faster, but harder to implement. There's also ConsoleKit magic involved in the G* implementation whereas for the K* one, the new X display just gets registered as a new session with ConsoleKit by the regular KDM ConsoleKit integration.
