At one time, there were patches floating around, but they were never
pulled in for some reason or another. The new cool thing is wscons(4)
and wsdisplay(9)..., but I can't see a trivial API to get the address
of the frame buffer. [rasops(9)?]

Probably best to stick to what you see in <mac68k/grfioctl.h> -- in
other words, GRFIOCGMODE, as undocumented as it is.
