Well I'm happy to say that X works for me.  It starts up, DRI is 
enabled.  Sadly, I only have one functional monitor, according to 
xrandr, and even that one doesn't report the full 1600x900 resolution 
that it supports.  xrandr maxes out at 1024x768.

DVI-0 is connected but, as you can see in the log file, isn't detected.  
DVI-1 is at least detected :-)

I saw this morning on https://wiki.freebsd.org/AMD_GPU that "EDID is now 
read properly so the correct resolution is used by X.Org."  So I made 
sure to pull the latest code on the kms-radeon branch from 
https://github.com/dumbbell/freebsd today and updated the kernel before 
reporting this here.
