KDE update for SuSE 9.3?

Hello, I am new to this list. Noticed, that all KDE supplementary resources moved to opensuse.org Now I am unable to update my KDE (SuSE 9.3) any more. (was interested in 3.5.3) The solution described at http://en.opensuse.org/Build_Service/User does not work for 9.3 + YaST. Yast needs the yast-sorurce folder (and it's content) to add a new installation source. How to solve this? BTW: where have the KDE supplementary packages for 9.2 gone? I think, 9.2 is still not discontinued ... Joe
