3/80 kernel config pitfall

[benson at odi.com]

The standard config file for the 3/80 lists the cgfour0 first, and the
bwtwo0 second.

By editing accident, I discovered that the system fails quite peculiarly
if you reverse the order! things are fine in B&W, but in color you can
only get pink and the pink tends to obscure black lines and text.

The sun support people want me to go do extra experiments to confirm their
bug. I'm not sure I have the time, so I'm passing the info along to the
rest of you.
