first stab at a driver for the cg12 / matrox cg3
for now it uses the same monochrome overlay as OBP, otherwise it's got the usual wsdisplay / vcons goodies TODO: - fill in mmap and ioctl methods so we can at least run X in monochrome - figure out where the 24bit buffer is ( and maybe if there's an 8 bit buffer ) - see if we can do any acceleration - find the DAC registers
