That actually sounds a bit more familiar... ISTR something in the kernel
framebuffer code explicitly forbids bpp=1 but that could be circumvented.
Any recollection of that, Geert?

OTOH, fb_ioctl just calls the atafb_check_var() and that's also used
internally to atafb. So it should work provided the var_screeninfo is sane
(and my modedb is sane as well. Now there's a thought).

No, sthigh is a strictly monochrome mode - I stole the generic mfb draw
primitives from Geert's mfb.c for that atafb mode (speaking of the

It's a shame that X does not support 16bpp packed pixels ...
