Might this Doug Lee be willing to give me some pointers on doing
likewise to mine? I have a 1600x1280 1bpp monitor I'd very much like
to get back in operation, but it dimmed into unusability. I'm pretty
sure I kept it against finding someone who could help it....

The bwtwo is about as dumb as framebuffers get. I think the only bits
you need to care about are the video RAM and the "video off" bit used
by screenblankers. (I think there's some timing goop and such, but
that's set up by the PROM code at POST and you don't need to touch it.)
The existing bwtwo driver should tell you everything you need, I think.

I'm pretty sure I've got a spare. I'll check when I get home.
