I've posted a patch to do that. Should we? Why? We lose information doing that. Instead of a nice linear 0-100% brightness scale, you are now back to an 8 or 16-level non-linear brightness scale. 0 to 100% is hardware agnostic. You know where the middle backlight level is. You know where the one quarter, and three quarter levels are. You don't know anything about the brightness level anymore, after you compress it to an array index. It is a step backwards IMHO. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
