My kernel, when either setting the backlight to 0 or snoozing, will switch off the LVDS transmitter and the DAC of the ATI chip. For some reasons, when I do that, the LCD "freeze" it's current display (sometimes, it also give the "melt down" effect). If you change the screen content, things won't get updated as the video chip is not transmitting. I can't tell if the LCD itself is still eating power when that happens, and I don't know (yet ?) any way to turn it off. Ben.
