So. Newer ati packages did not improve.

I then decided to start from a clean base, no debug Xorg, no debug
radeon driver etc.
I cleaned, deinstalled and reinstalled first the xorg-server then the
dri and afterwards the same for the xf86-video-ati. The order of dri and
ati does not matter I think.

Having done this, I was able to run the 3D-demos.... yeah!

The kernel has WITTNES and friends commented, also DRM_DEBUG is off.

Here the excerpts from the Xorg.log:

X.Org X Server 1.7.7

Module radeon: compiled for 1.7.7, module version = 6.14.3
