recent rasops commits vs. macppc

[Michael <macallan%netbsd.org@localhost>]

Hello,

I just tried to update a few macppc machines and found that every one
of them crashes early during kernel startup, before the copyright is
printed. Rolling back dev/rasops/ to july 1st allowed them to boot.

I didn't have time to investigate further but, as a data point, macppc
early console uses 8bit colour and a bitmap font, scribbling into a
firmware-provided framebuffer.

have fun
Michael
