That's true, I in fact never used the VGA port on that board. 
Currently, the display parameters are hard-coded for a Sharp LQ43 which
is gross, I admit. But I haven't found a nicer way yet.

The board uses a dumb video DAC (ADV7125) to transform the parallel
LCD signal data to serial VGA. You should be able to make that work by
supplying the correct settings to set_pxa_fb_info().

That's something I never heard about. Ethernet was working properly here
ever since I tried it. More information would indeed be important.
