Looks perfectly fine to me ( the photography that is, not the actual

I see the blur. And I bet they're running on different frequencies.
Looks like I'll have to go and see if I can make radeonfb use whatever 
mode it finds. The problem is that I didn't write the driver and don't 
have Radeon docs.
Odd thing is - your firmware seems to know which mode to use but I 
didn't see EDID data anywhere, neither in radeonfb's output nor in your 
OF tree.

have fun
