Looks like r200 is correct for newer Radeons.  Adding R200 to DRI_DRIVERS in
/usr/ports/graphics/dri/Makefile and rebuilding/reinstalling the port made
it available, but apparently it was disabled for reason, as it doesn't work:

  (II) AIGLX: Screen 0 is not DRI2 capable
  ...
  (EE) AIGLX error: r200 does not export required DRI extension

libGL with verbose debugging also reports:

  libGL: screen 0 does not appear to be DRI2 capable
  libGL: XF86DRIGetClientDriverName: 5.3.0 r200 (screen 0)
  libGL: OpenDriver: trying /usr/local/lib/dri/r200_dri.so
  libGL error: failed to load driver: r200
  libGL: OpenDriver: trying /usr/local/lib/dri/swrast_dri.so

Does NEW_XORG implies DRI2, or there's a fallback of some sort that can be
used as a workaround?
