Hi all,

I've been doing some work on the Apple backlight driver in the Linux
kernel to get support for adjusting the screen brightness via the gmux
device. This will hopefully get working screen brightness adjustment for
all Macs that that don't currently have it. This support has been
floating around in various forms for a while now, and what I'm trying to
do is get it into stock Ubuntu so brightness adjustment will work
out-of-the box, more or less.

The driver changes are pretty much complete, and now I'd like to get
testing on as many different Apple models as possible. If you've got a
machine with a built-in dispaly and would be willing to test, please
visit the following page for instructions on how you can help.

Thanks for helping! Feel free to contact me if you have any problems
with the instructions or encounter any problems with the test driver.
