For G45/GM45, the hardware has built-in DP support, but the driver
doesn't work with it yet. I'm working on it, but it's harder than HDMI
to get running. I spent a day and got the chipset talking to the
monitor, but no output yet. And no EDID yet either; the DDC stuff uses
the DP AUX CH in a mystic way.
