It has been way too many years since I've used ARI/AMD video. I'm going to
assume here that you are trying to utilize the on-chip AMD/ATI, and not a
second discreet card. These may be of interest:
https://wiki.freebsd.org/AMD_GPU
https://wiki.freebsd.org/Graphics
On the Graphics page in the section "Video driver loaded at boot time" is
example of the kernel modules to load. When you look in /boot/kernel you
will see a radeon.ko and a radeonkms.ko followed by a bunch of other
firmwares which are needed by various models. Many seem to have the model
name embedded in them and I don't see a particular one with 'Jaguar' in it
(this is a 10.1 machine I'm looking at here). I believe that even with these
modules loaded you will still need to install the appropriate driver for
Xorg under ports/x11-drivers (which still may not support Jaguar yet). It's
also a possibility that the xorg driver may support, but the kernel modules
and firmwares haven't caught up yet.
What I don't have any clue is the exact support for the specific chip you are
trying to use; it may not exist yet or may be a WIP. Maybe there is some
bleeding edge patch or code around somewhere you can try if nothing
currently in Release is working.
