As a general practice avoid altering distribution supplied scripts as they may 
be replaced when updates are applied.  You then have to make your changes 
over again.

In prefdm, the variable DISPLAYMANAGER is expected in the file 
/etc/sysconfig/desktop and is sourced (the "." command or its bash alias 
"source" may be used) as you see in this code snippet from prefdm.
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

The DISPLAYMANAGER variable does not exist by default.  Edit this file and 
place your DISPLAYMANAGER=KDE line in it.  No spaces on either side of the = 
sign.
