Thanks for the reply.  After I reached out to this list, and after doing
some (inconclusive) research on this topic -- and my ignorance of AMD, I
found out my problem: the FreeBSD handbook says to add kld_list="amdgpu"
to the /etc/rc.conf file, but I missed to additional steps needed (may
be in a different section of the handbook) which were to add two ports:

   graphics/gpu-firmware-amd-kmod
   x11-drivers/xf86-video-amdgpu

Once I built and installed those two ports, Xorg/x11 graphics worked
flawlessly on the Thinkpad T16.  Thanks again for your information.
