I'm happy to report that my EDID problems are gone, and an quick initial 
test of the r600 gallium driver shows:

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CAYMAN
OpenGL version string: 2.1 Mesa 8.0.5
OpenGL shading language version string: 1.20

It took some editing of the graphics/dri port to even get it to try and 
build the r600 gallium driver, and then I had to get the build to 
include /usr/src/contrib/ofed/include/infiniband/byteswap.h.  I haven't 
had a chance to test anything else (as I'm not in front of that computer 
at the moment), but it's looking good so far.
