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
