Good question, all 2 or 4bit displays I've ever seen either use 
separate 1bit planes or packed pixels ( 2 or 4 pixels in one byte ). 
There's a 4bit catseye-like framebuffer for hp300 if I remember 
correctly, but it should use 8bit pixels.
I /seem/ to remember some mono-in-8bit framebuffer that wanted 0xff for 
a white pixel and everything else for a black one ( which ended up as 0 
when read back ), but that could be my flaky memory.

have fun
Michael
