ok, Got it now.

I disabled the VESA fb framebuffer and added the radeonfb instead (want my penguins during boot). This did it.

You don't need radeonfb; it doesn't even support your chip. The radeon KMS drm provides a fb interface itself. radeonfb is an old fbdev driver from the pre-KMS days and will conflict with the kms drm on chips supported by both.
