I believe that the file "/etc/X11/prefdm" is what you want to tweak. 
There's a part in that file that says the following:

# Run preferred X display manager
preferred=
if [ -f /etc/sysconfig/desktop ]; then
        . /etc/sysconfig/desktop
        if [ "$DISPLAYMANAGER" = GNOME ]; then
                preferred=gdm
        elif [ "$DISPLAYMANAGER" = KDE ]; then
                preferred=kdm
        elif [ "$DISPLAYMANAGER" = XDM ]; then
                preferred=xdm
        fi
fi                                               


Now, in the part where it checks $DISPLAYMANAGER for GNOME, just tweak
that to kdm instead of gdm.  Then, so that the new display manager (kdm)
takes effect, just do an init 3 followed by an init 5, and that should
do it.
