I would be very interested to know if this actually works for you.  I 
have a PCI-E 6200 with DVI hooked to a projector via DVI->HDMI cable.  I 
could never get CustomEDID and ConnectedMonitor actually result in a 
live DVI port without the projector turned on.  Now, an X session is 
created that I can VNC into but the port is not live when I power up the 
projector.
