With my i965 and a monitor _with_ EDID connected to the VGA output, I do 
get flickering (the screen turns black for one second). So, it seems the 
flickering happens all the time. Is it a bug in the intel driver? Or 
maybe it's because there is also a TV output? (that would be nasty 
because the laptop don't even have the plug!)
