Minimal driver for the VAXstation 35x0/38x0 LEGSS option, currently limited
to 8 bit mode operation, and no color or accelerated features until I can
find documentation about it.
Speed is decent by VAX standards, except for scrolling, which is so
abysmally slow one could see ZZ Top's beards growing while waiting for the
screen to scroll...
