Brightness control on notebooks

# cat /proc/acpi/video/VGA/LCD/brightness
levels: 100 37 12 25 37 50 62 75 87 100
current: 50

# echo "any of the above numbers" > /proc/acpi/video/VGA/LCD/brightness
/proc/acpi/video/VGA/LCD/brightness does not exist? Try:
# modprobe video
To load automatically:
# echo video >> /etc/modules
Works on my Dell Inspiron 1501 running Debian Etch (kernel 2.6.18-4-k7).
