2. Is radeonfb really supposed to be compiled into the kernel as it is, or should it have been built as a module? Why do you think they compiled it into the kernel?
It was traditionally done like that on powerpc to provide a nice console experience and suspend/resume support on laptops.
3. If the kernel is activating radeonfb as we can see in dmesg, why would it also load the drm/radeon driver?
Presumably, the radeon driver is loaded by udev because it declares that it supports your GPU. It could still be used by older upstream versions of xserver-xorg-video-radeon and libgl1-mesa-dri, but the current versions only support KMS anymore.
I believe I answered your other questions in my previous two e-mails. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer
