Sure. top readings for memory have a history of being annoyingly easy to
misunderstand (read: being wrong). IIRC these memory readings show all mem
used by shared libs as belonging to the app, so these are displayed multiple
times.
My X mem numbers are probably disturbed by the Nvidia drivers. Who knows what
these actually do behind their proprietary scenes...

I have 512 meg of RAM, and the machine never swaps under normal use. Basically
I don't care for the memory usage, as long as I have the impression of
getting something in return, and using KDE I certainly have that impression.

Adding more RAM does not improve the situation either. Logging in takes almost
1 minute on my AMD 1200/512meg. Starting kwin manually from a failsafe X
Session is almost instantaneous. Same for kdesktop... startkde OTOH takes as
long as a usual login...
