If we're making a whole new architecture, adding a blitter or a real DMA 
controller wouldn't be out of the question. That would offload at least 
some of the video chores from the CPU.

My personal opinion though would be to limit it to 15/16 bit color. At 
least those pixels would fit in one 16 bit register nicely. :)
