If you are on 7.1 then it can't be drm.  The chip that you have is the
one that apparently behaves like a 965, but the output looks reasonable.
I have patches for RELENG_7 that should enable drm as well.  See my
"latest drm patches" thread on freebsd-x11_at_.  Both of these are now
committed to HEAD.
