There is a mono driver called vga2 and a program called X386mono but I
cannot run it.
	Then it will be 8 times faster but you only have 2 colors, black and
white. I used to think that 8-bit is too much but when I run the XFree86, it
is so fast that there is no need to speed it up by 2 time. I'm only using
a non cached 386 25 Mhz without 387.
	In fact 16-bit is the ultimate. There is no need to go any futher.
The 24-bit and 32-bit DACs are wasteful because they do not take into account
human visual perception.
	At least that is what TV textbooks say. Is there any recent work proving
otherwise?
