I have a problem with aux/vga and my Quadtel S3 video board.  The standard
/lib/vgadb entry wasn't working so I looked at the board and saw it had a
att20c40-80 chip in in so I changed the ramdac entry, and then reordered
link=3clock ... so it was before the ramdac entry (don't ask me how I
worked this out :-) and changed the clock field to be icd2061a.

Then I run aux/vga -l and the weirdest thing happens:  I get two half
screens, side by side, which are identical; the mouse tracks in both
and 8 1/2 runs fine.  I think I'm close at this stage, but I'm at a
loss to understand what's happening (the only thing I know about PC
hardware is that diskette rhymes with whiskette).  Any clues?

The aux/vga and /lib/vgadb I have come from the pre-release that we have here.
