Let's forget the older version driver in the original report, and stick to the latest git code.
So the detection is correct, and the only problem is blank tv or vga screen. Let's focus on LVDS+VGA first.
Please attach the full log of that, with ModeDebug enabled, according to http://intellinuxgraphics.org/how_to_report_bug.html.

a single line of "underrun" normally doesn't hurt.
