Can it be that the behavior of ksmserver has changed?
Have a look in  /opt/kde3/bin/startkde. When in multiwindow mode, ksmserver
is started with '--windowmanager unknown'. Obviously 'unknown' is not a valid
window manager. The current version of ksmserver then starts kwin. If you
change the following line of /opt/kde3/bin/startkde:
KDEWM="unknown"	# dummy name to avoid loading of a window manager
KDEWM="wm"	# dummy name to avoid loading of a window manager 
then kwin is not loaded and multiwindow seems to work, although I don't
know the implications of running ksmserver with --windowmanager wm.
