Bug Description

Binary package hint: linux-image-2.6.28-4-generic

/sys/class/backlight/ is empty on my dell 9''
It prevents any tunning of the backlight level.
Iµm not sure of the last kernel version providing me with a non empty /sys/class/backlight/

For info, /sys/class/backlight/ is *not* empty with a 2.6.27-7-generic (from the kubuntu 8.10 livecd)
See the corresponding dmesg.
