Hi again on this issue,

yes, I got it! 

 - get original binary Xfree 4.0.2 from www.xfree.org (.tgz packages
   with nice install script)
 - in case of NVIDIA: Install additionally their drivers
 - install MESA GLU and GLUT (but not GL!!)

 -> enjoy high speed NVIZ (maybe 10-800 times faster)
 -> enjoy high speed vis5D
 -> enjoy high speed Mesa demos

It's great. Note: The Xfree4.0.2 from SuSe is quite instable. I wasted
much time on it, finally replacing it with original Xfree version.

This should work with any 3D-video card as the original Xfree detects
it (if supported).
