I see the u-boot console with an sweet Tux in upper left corner on the
monitor connected to the radeon card.
So I say: Yes, it is working.

When I start Xorg with framebuffer driver (after radeonfb was loaded),
this is working, too.

The xorg radeon driver with drm/radeon kernel modul loaded is not
completly working.
I will inform you in the next days. Today I have no time anymore.
