This board is incorrectly detected as having an LVDS connector,
resulting in the VGA output (the only available output on the board)
showing the console only in the top-left 1024x768 pixels, and an extra
LVDS connector appearing in X.

It's a desktop Mini-ITX board using an Atom D525 CPU with an NM10
chipset.

I've had this board for about a year, but this is the first time I
noticed the issue because I've been running it headless for most of its
life.
