Aaaahhhhh.... Am I this blind? Now I see exactly this.

Also in dmesg log I see RS400 being written out so yes I end up here and
according to my own links this seem to be the problem that the rs400_gpu_init
should not do the r420_pipes_init, because it is not r420 yet....
Now after investigating I think I should indeed end up here with the
rs400_asic, but yes the 420 pipe setup is wrong - at least for my card.

I will run with this patched and see what happens. The machine can compile the
kernel through the night for testing this...

This seems to be the real core of the issue.
