Langdon,
Are you trying to use the new kernel from colorkit? If not, I do not
know the solution for you. I have exactly the same hardware and it works
without problems.
If you are using the kernel with color support, I would expect the
effect like you described. The kernel switches to 1-bit mode at driver
probe stage and your video memory become meaningless. If you look at
your computer from a distance, random lines will look like letters :)
Try set 1-bit B&W mode before booting and see what happens. The screen
should blink but remain readable.
I would also suggest for you to subscribe to port-mac68k mailing list.
Look at http://www.netbsd.org for information.
