Hi,
thanks for your hints. But at the moment, I'd be lucky if I could get xorg
working with dual head even without radeonfb. It would be nice if I could
have a framebuffer console, though. Is one of these patches about to get
in mainline? I (have to) work with new kernels all the time, so it would 
be quite inconvenient if I had to apply (and maintain) an out-of-tree
patch every time I compile a new kernel.

If one of these patches looks acceptable for the fb-devel folks, I'm
willing to review, test, and submit updated patches if it works.

Thanks,
Hans
