Sorry, I may have not been clear...
You want this in /etc/sysconfig/desktop
DISPLAYMANAGER=KDM
Note no preceeding dollar sign :)
To better understand, take a peak at /etc/X11/prefdm
In it, its doing this:
. /etc/sysconfig/desktop
You'll see it doing some checks like:
elif [ "$DISPLAYMANAGER" = KDE ]; then
preferred=/usr/bin/kdm
Which will be used in starting kdm :)
