It looks like those options are specific to each driver, and there does not seem 
to be any standardizations among them.

Other possible ones are:   DDCmode and DDC

You might also be able to use:

  Option "MonitorLayout" "[type on primary], [type on secondary]"

where types are:
             NONE   -- Not connected
               CRT    -- Analog CRT monitor
               TMDS   -- Desktop flat panel
               LVDS   -- Laptop flat panel

And select NONE for the secondary to disable it.

The EDID stuff always annoys me, my old 20" monitor does not appear to return 
proper info for its top resolution even though the original docs list it as 
supported at the given resolution and refresh rate.
