Public bug reported:
beginning with 3.4-rc1, backlight control seems to be not working for my laptop.
the keyboard shortcuts have no effect and the backlight settings are not
displayed in gnome-control-center.
I compiled the latest 3.3.y-series stable kernel from kernel.org and those
things just work fine.
but it neither works with the latest kernel from the quantal repository, nor
with the latest kernel from kernel.ubuntu.com/~kernel-ppa/mainline.
