Pushing RGA through the DVI port with open-source drivers.

[Jeffrey Gray]

Well, the three cables are your RGB signaling.  VGA is RGB with a
vertical and or horizontal sync (or something of the sort)  I don't
see why you couldn't use that cable and have it work at the hardware
level without worrying about drivers.  The 4 pins surrounding the
blade ensure that the DVI connector can not be plugged into a DVI-D
(digital only).  With the DVI-I the port is outputting a DVI signal on
some of the pins and the old analog RGB signal over others.

Just my quick thought.
