The first batch of sources has been pushed to gitorious. These commits are intended mainly to check that the classical (forward) renderer is not broken and works as usual. They will also permit one to challenge his GPU and see how it behaves in front of the beast.
In the plan exposed previously (see below), I skipped step 3. (define an XML format for a configurable renderer) as it appears to be more involved than expected. So what you have is a buggy step 5. :) Buggy because for some reason, sun light depends on the orientation of the camera. But you should get an image. The Rembrandt renderer is enabled with the --enable-rembrandt option. *ALL SHADERS SHOULD BE SET TO OFF* unless someone want to begin to convert other shaders.
