You're supposed to add extra package sources for the local suse mirror.
Check out opensuse.org/download to locate your closest mirror and then add all the Suse approved install sources located in the sticky in the Suse Forum.
Then once you add them all, you'll want to make sure "Refresh" is on for all internet sources and then go to Software Management and select "Installed Packages" from the drop down. Check the "Keep" box and in your list you'll see some packages red, black, and blue.
Blue = update available
Red = you have a newer package installed than whats available (dont touch these)
Black = package installed.
So basically, just click all the blue packages so they have the "lightning bolt" next to it and then click Accept. The "lightning bolt" is to upgrade package.
Once its all done, then reboot and you should be good to go.
I'm on KDE 3.51 and it works great.
