Clemens,
I don't know if this has any relevance now, but I experienced similar poor
performance a while ago with a machine who's configuration was very
similar to yours (Athlon 1000, Nvidia FX5200) and it seemed related to the
Nvidia binary driver current at the time (a couple of years ago). The
driver worked well for 3d applications (glxgears gave much higher fps) but
seemed to devastate the 2d performance particularly with GTK2
applications. Changing back to the open source 'nv' driver seemed to work
much better. I never knew whether the problem was hardware or software
related and eventually swapped the graphics card for an inexpensive radeon
using the OS 'radeon' driver. This combination worked much better for me
so I never investigated further.
