This part got cut from my first post. The handbook says:

     To generate the configuration file and start the X system, issue
     this command:

     % startx

This is clearly wrong. 5.4 also says autoconfiguration is the preferred method. 
I found a post to on 8/4/15 from wblock@ saying: 
"Auto-generating xorg.conf is not recommended any more."

Hence my confusion. The next part I understand and will try. But it seems to me 
that Xorg -configure, if it is there, should work. I was asking should this be 
reported as a bug (I could find nothing) or is there another way just not 
documented yet?

If this not a depreciated method, I can report it and/or provide all the data. 
That was not really my question as clearly the radeon driver works. Again I was 
going for, "is this just a documentation error"?

I assume I can then also add the font commands as needed. I could find no 
documentation in the FreeBSD wiki or on Xorg that indicated X would just piece 
all this together. I assume this would now go in /usr/local/etc/X11.
