prefdm references /usr/lib/kde2/bin/kdm, which doesn't exist in RC2, and
therefore makes putting DESKTOP="KDE2" still use gdm, not kdm (as expected)
If KDE2 isn't a valid entry in /etc/sysconfig/desktop (it isn't listed as
such in initscripts' sysconfig documenations), can we just delete the two
lines referencing KDE2 in prefdm? This would make prefdm less confusing.
Fixed in CVS, will be in 5.71-1.
