Ug. Now that several drivers compile now I get bug reports :-( I'm getting
alot of positive feedback as well as one negative source.

Okay. That is weird. I have this card so I will give it a try.

Yipes. Imageblit sounds broken.

I noticed this. The color palette is for some reason messed up.

Same things. Color palette is messed up.

Yeap. I migrated changing the console from /dev/fb to actually using the
tty layer. I haven't merged those changes yet but you will be able to do a

stty -f /dev/ttyX 80 col 50 row

and change the video mode.

So I didn't plan to push so soon but I kept getting emails about various
drivers being broken. So I did this push to make more drivers work.
Unfortuenly I sent a watered down fbcon system.
