Same thing happens to me.
With i810 drivers everything works. Even the fn-F5 key cycles between LCD, CRT, 
LCD+CRT...

with intel driver xrandr reports VGA monitor connected (When I connect it), and 
with the same resolution and position that the LCD one, but the external 
monitor doesn't wake up.
In the debugged logs I can see that the Samsung monitor or an external EPSON 
projector is detected and the EDID chat is done. But I have no signal.

I can turn off the LCD and it works. I can turn it on by typing blindly,
and it works, but when I change any VGA output setting, even when xrandr
reports the settings has been applied, nothing happens.

I think the problem could be the VGA power saving option that keeps enabled.
Anyone knows how can I interact directly with VGA card energy saving settings.
