The CF-A44 is way too slow to use modern versions of KDE. Even applications which use the KDE (QT) interface suffer, such as lyx-cjk. icewm is a good, fast replacement for KDE. Unfortunately, it does not have an inbuilt drag-and-drop file manager. icewm also looks awfully like Windows...
`xfce' does have file manager, but it is not fully supported by SuSE.
