Can anyone help me set up my XF86Config file? I am using a single
board computer that has a flat panel header, and also a standard VGA
jack. The VGA works fine, but I can't figure out how to activate the
flat panel header.

I have tried using a modeline that is specific to my panel (its an NEC
NL6448AC33-29, 640x480, and I set up a very standard modeline according
to the datasheet.)

The modeline I used was:

"640x480@60" 25.17 640 656 752 800 480 492 494 525 -hsync -vsync

My problem is no matter what I try, the panel header is inactive (I am
probing with an oscilloscope, and there is no activity.)

Are there options I need to specify for this particular driver to get
both the panel and the VGA working?

Thanks
