Is backlight off or is it enabled and just screen content is

The screen content is black, I can change the backlight intensitivity
with my keyboard.
wrong size detected, display is 1680x1050.
That's interesting.
Enable radeon debug options and send me the output.

Also try
commenting out the call to radeon_map_ROM(rinfo, pdev);
in drivers/video/aty/radeon_base.c and send me that output
as well (send me both, even if commenting out the call "fixes"
it).
yes, it fixed the problem for me (I get an working framebuffer, computer
still crashes (sysrq still works) on startup (via xdm)).
