    Use existing "Dualhead" option in MSOC.
    
      If Dualhead is set, it will attempt to use setups that allow different
    outputs with different contents, instead of crt always cloning panel.
      Still not fully functional.

    Crt interface corrections.
    
      Correct wrong clock calculation for the 501 clock setting, that is used
    for pre 502 panel interface and crt.
      Adds a few new programmable fields to MSOCRegRec:crt_display_ctl.
      Call SMI501_CrtcAdjustFrame() after adjusting a mode, instead of
    before changing registers.

    Don't change M1XCLK unless option specified in xorg.conf.
    
      Also add more complete description of programmable clocks.
