YaST2 integration into the KDE Control Center ?

Hello SuSE folks, It's a very strange situation. As soon as I upgraded KDE2.0 to KDE2.1 from SuSE web site YAST2 modules just vanished from KDE Control Center. Although they installed and present in the system. Could somebody tell me please how can I return them back into KDE Control Center? Thanks.
