++ *
++ * Set a single color register. The values supplied have a 16 bit
++ * magnitude which needs to be scaled in this function for the hardware.
++ * Things to take into consideration are how many color registers, if
++ * any, are supported with the current color visual. With truecolor mode
++ * no color palettes are supported. Here a psuedo palette is created
++ * which we store the value in pseudo_palette in struct fb_info. For
++ * pseudocolor mode we have a limited color palette. To deal with this
++ * we can program what color is displayed for a particular pixel value.
++ * DirectColor is similar in that we can program each color field. If
++ * we have a static colormap we don't need to implement this function.
++ *
++ * Returns negative errno on error, or zero on success. In an
++ * ideal world, this would have been the case, but as it turns
++ * out, the other drivers return 1 on failure, so that's what
++ * we're going to do.
