X11 not working on 11-STABLE with AMDGPU

[CL Moonriver]

The only thing that actually worked for me was the kms module loaded in 
rc.conf. Any attempt to configure the display in xorg.conf resulted in 
an X server that would not start, but would continue running for awhile 
and appear in the process list before it finally gave up. But again, I 
must have an older AMD GPU because it uses the radeonkms driver instead 
of amdgpu. (It's an AMD A10-7860k with Radeon R7 graphics)

On another note, I'm using UEFI boot. Based on my limited understanding, 
I think that means X is actually using the scfb driver, which is not 
ideal from what I understand (no accelerated graphics). But it works 
fine for what I do, and it's the only configuration I could get working.
