the radeon driver defaults to driving each display with a separate crtc (called
clone mdoe).  if it can't find the DDC data for the attached monitor it defaults
to 640x480 at 60Hz to avoid potentially damaging you monitor.  You can either
disable clone mode (in which case crtc1 will drive both outputs) or add the use
the clonehsync and clonevrefresh options (to tell the driver the monitor's
limits when it can't get DDC data).  see that radeon man page for more about the
options.
