Here's a curious data point: If I boot my laptop from cold with a flat battery, the POST, grub, boot sequence and X will all run with a dim screen. If I then hibernate to disk and resume once the battery has a little more juice, the brightness is back to 100% for POST and grub...until some point in the resume sequence, where the brightness then goes back to being dim. So, I think this means that backlight brightness is controllable, somehow, but just not in a way that's useful to the user :-)
