Are there any AMD graphics blobs available?

I desperately needed a couple of additional "build boxes",
as I'm currently MAINTAINER for ~110 ports, and am RP for
more servers than I care to recall. So around mid December
of 2016 I dropped ~$550 on some AMD based boards. I've
always used boards with nVidia onboard graphics in the past,
as the Intel/AMD/ATI/... graphics support was still
"ramping up". Anyway, the FreeBSD Graphics wiki
(https://wiki.freebsd.org/Graphics) indicated everything was
in HEAD, and or CURRENT. So I felt safe going the AMD/ATI
route this time.
Long story short; I can't get any usable video. I'm not
sure how to better provide useful information. According to
the "Video decoder ring":
(https://www.x.org/wiki/RadeonFeature/#index5h2)
I'm supported. videoname -a doesn't produce anything. ;-)
The only reason I'm able to use one of the boards to write
this, is because I shoved an old nVidia pci card into the
pci(32bit) slot. Which makes it unbearable -- honestly,
it moves as fast as a 486. The output can't even keep up
with my input on the keyboard. :-(
FWIW

For brevity; some additional details, and history can be found

Please tell me I didn't just waste $550. :-)

I can provide any additional details, as required.

Thanks!
