Public bug reported:

Binary package hint: linux-image

brightness steps are reversed as reported by lshal.  This causes the Fn-
Home and Fn-End buttons to work in reverse, and the brightness increases
on idle, etc.  The link below has a patch to fix video.c in the kernel,
it will implement a sort on the brightness values.  Please implement
this for us ubuntu users and help push it up to the linux kernel.

gary at gary-laptop:~$ cat /proc/acpi/video/VGA/LCDD/brightness 
levels:  100 90 85 80 75 70 65 60 55 50 45 40 35 30 25 20
current: 25


I have a thinkpad SL300 with intel GM45 graphics.
