 * HAL/gnome-display-manager really wants us to only set 8 different levels for

 * overkill, that's fine.  So let's map the 256 values to 8 different ones:
 *
 * userspace	 0    1    2    3    4    5    6    7
 * hardware	31   63   95  127  159  195  223  255
 *
 * or hardware = ((userspace + 1) * 32)-1
 *
 * Note, we keep value 0 at a positive value, otherwise the screen goes
 * blank because HAL likes to set the backlight to 0 at startup when there is
 * no power plugged in.
