The Pandaboard list seems dormant so I am seeking help here.
The previous kernel with HDMI video output was 3.2.7x5.
I built and installed this new kernel with this xorg.conf, it does not
work.

Using the udlfb driver and an xorg.conf for the Lilliput USB 7" screen
there is no problem, LXDE is up and running and CRTL-ALT-F1 etc. all
OK, but I need the USB screen for the Beaglebone.
