This is what you're using for the Indigo. We have specifications for the
newport chipset that can be found in most Indys. You can do a lot of things
with the newport chipset such as DMA transfers directly from memory. For the
newport console that's in drivers/char/video currently use a method where we
set a window with the size of a character and then repeatedly set a register
on the newport to different color values. There are also functionality for
drawing lines and some other goodies built in. A framebuffer could be
emulated, but it would be rather slow.
