When loading the radeon module with modeset=1, the kernel oopses:

Yes, I've tested with the firmware binary from
http://people.freedesktop.org/~agd5f/radeon_ucode/ now and it works. It seems
a fallback path is missing if no firmware is found.

It should fallback properly if no ucode is found in airlied's drm tree at least.
