Support for parts covered by radeondrm (SI, CIK) is not compiled into the amdgpu kernel driver. There is no support for Navi in the linux 4.19 based code and Vega 20/Radeon VII support is prelimary and disabled. There are still problems with amdgpu compared to other drm drivers, it was enabled as people considered the current situation an improvement over not having it. I'd rather leave the xf86-video-amdgpu man page as is.
