The d-sub port works fine.  You are using an old version (6.6.193) of
the radeon driver that does not support xrandr 1.2.  You'll need to
upgrade your driver to 6.7.19x or 6.8.0.  Also, since you are using
Xorg 7.2.0, you may have to upgrade your X stack (or at least your
xserver) depending on what xserver version your distro included.  You
need xserver 1.3 for xrandr 1.2 support.
