  Reducing the recursion_limit hit the spot (although I realized that before
reading your suggestion). The render time also reduced from 1.5h to 1h.
  I made a second entry which looks much better.

  Well, speedwise I think that meshes and imagemaps are quite ok. If that
same scene would have made with primitives and procedural textures, the render
time could perfectly be several hours...

: How did you convert it BTW?

  3DWin4 did a damn good job at converting the 3ds file given in the page
to mesh2's (with the original uv-information, of course; without that it would
have been impossible to render the scene).
  As the 3ds file didn't have the actual imagemaps, I had to search and
set the proper images in proper places, but that wasn't too difficult.
