I tend to agree on limited usefulness of VGA in embedded. However, not
having embedded video is one of the reasons it was decided that the board
be a sub-port of evbarm rather than a port of its own. Based on that, it
seems something along the lines of video capability may have merit for
NetBSD, if nothing else than from a marketing standpoint among other
potential NetBSD users.
There are some cute (literally, QT :-)) APIs that are more applicable to
doing graphics on non-x86 embedded systems. For a lot of embedded uses,
even that may be overkill when all the designer really wants is access to
a framebuffer. Running X itself is actally not that far off with 200Mhz+
Its also worth mentioning that Cirrus Logic has embedded video on its
other ep93xx chips. Its tailed for >=QVGA graphics on LCD/TFT.
We use DOC's on a lot of our x86 products. Our experience with them has
been similar to yours (bad).
