[parisc-linux] HP1825 and PCI Vis-EG at 1600x1200

I tried 1600x1200 @ 75Hz on a NEC LCD.  However, I found that the
redraw time with the VIS-EG was too long for my taste.  I settled
for 1280x1024 @ 75 Hz.

The C3k manual describes the commands needed to the Vis-EG 
to its predefined modes.

If I recall, there is a line in the list of settings for the
Vis-EG for user defined settings.  However, I couldn'd figure
out how to set them.
