Verified. Setting CONFIG_FB_RADEON=m and rebuilding the kernel fixes the
radeon problem on my Mac Mini G4 PPC permanently. Since there are
several framebuffer drivers compiled into the kernel instead of building
them as modules on the PowerPC kernel, I suggest to build these as
modules as well to avoid the very same problem for other video adapters.

I will provide a proposed diff for the kernel configuration on powerpc
