No, but I was missing something. I've re-read the code and now it's
clear to me that one of my preconceptions about how this is supposed
to work was mistaken. Sorry for the confusion.

OK. Then I'll probably wait until wscons is ready to begin my
efforts. It's a real pain to work on the silly thing anyway, now that
my TT's VME slot is taken up by the ethernet card.
Since as far as I know I'm the only person with a Leonardo graphics
card running NetBSD/atari (I believe only three of the cards were ever
produced), my true goal in working on the driver at all is to learn
more about NetBSD internals -- so that I can apply that knowledge to
more useful things in the future. I think I've managed to accomplish
that goal this time, without writing a single line of code :-)
entropy -- it's not just a good idea, it's the second law.
