 I read a topic in unitedbsd, someone can resolve a similar issue with
 rebuilding the kernel, with comment out the two radeon related lines,
 and uncomment the 2 amdgpu lines. I did it, modified the GENERIC conf:
 #radeon*        at pci? dev ? function ?
 #radeondrmkmsfb* at radeonfbbus?
 
 amdgpu*         at pci? dev ? function ?
 amdgpufb*       at amdgpufbbus?
 
 but for me it doesn't work with modesetting Xorg driver, I get system
 panic when I start X, as earlier. (However I don't understand why this
 rebuild can work for anybody, as I see it is the same driver, just the
 amdgpu now inside the kernel not a module..)
