	The right ones are loaded automatically by the main radeonkms
driver - at least that's what happens with the amdgpu one. You almost
certainly need to compile the drm-kmod port to get things working -
installing the package is a recipe for panics IME.

	I gather that for radeonkms the radeon dri driver works but for
amdgpu (my laptop) there's /usr/local/lib/dri/amdgpu_dri.so wanted by Xorg
but I can't find it anywhere.
