This is likely a hardware restriction in the video controller, perhaps
a poor RAMDAC or some such (I'm not a massive expert on graphics
controllers) as I have a Quadra 840av (which has very nice video
hardware :-) ) and it will run right up to 1152x870@16-bit on 2MB of
VRAM. You can't use the video system in anything but black & white at
that resolution however! The majority of Mac II and Quadra machines
were designed to be used with high-end NuBus video cards. If anyone has
ever used a Radius Thunder IV GX they know what I mean ;-)
Not totally relevant to mac68k NetBSD I felt I had to make a
contribution somewhere ;-)
