Hi,
unfortunately Mandrake is not making kde 3.3 available as .rpm's neither for 10.0 ogr 10.1 at present. To get it you would have to compile it your self. There is a tool available on kde's website called konstruct on
http://developer.kde.org/build/konstruct/
this simplifies building things. It is also a lot of help text on how to do it. I am a novice when it comes to Linux, but I managed to use it and have found out that I needed to install a lot of packages first. And I still have a few problems I haven't been able to tackle. If you are going to o it I could supply some (hard earned) experience.
