It supports RASTERCONSOLE only and the colormap support is broken (the hardware doesn't seem to be doing what the tech. docs. say it should be doing). But it is usable as a console (but with blue on white as the only color choice). I figured I'd check it in since it is somewhat usable and someone else might figure what I screwed up in the color map support.
