First, no we do not give up on this, but things can get delayed by the
bulk of other things.

@gidantribal, I saw that the test kernel did not help (or made things
worse?). Could you post the dmesg from that kernel and 'grep -r .
/proc/acpi/video'. Is the brightness changing when changing the values
in the acpi brightness attribute?

The Jaunty kernel should not have the same specific problem as Intrepid.
Intrepid has a bug where acer-wmi stops controlling brightness when
there is no acpi brightness support. But it should do that when there
_is_ support. This is fixed in Jaunty but apparently there are other
issues as well.
