    Make Dualhead option functional.
    
      Slightly change clock selection code to start using 501 compatible values,
    before checking 502 values, if it is a 502.
      DPMS for the VGA/second output was being set with bits inverted, that is
    dpms-on was programmed as dpms-off and vice versa. This was one of the
    reasons of dual head not working.
      Corrected wrong vsync programming for the crt. Cut&paste/typo caused
    programming vsync with hsync values, and thus, never getting the crt
    to accept the mode being programmed.
      If adding:
      Option "Dualhead" "True"
    to xorg.conf, now you should be able to do things like:
    $ DISPLAY=:0.0 xrandr --output VGA --right-of LVDS
    $ DISPLAY=:0.0 xrandr --output VGA --below LVDS
    and so on.
      *Iff* there is some way to not have any limitations for video playback,
    this option should be made default or automatically configured.
