This article describes, how to enable the leds:
First obtain the kernel sources
ss4200:# apt-get install linux-source-2.6.26
ss4200:# cd /usr/src
ss4200:/usr/src/linux-source-2.6.26# tar xvjf linux-source-2.6.26.tar.bz2
ss4200:/usr/src# wget http://merkel.debian.org/~jurij/2.6.26-2/i386/config-2.6.26-1-686.gz #obtain standart kernel config
ss4200:/usr/src# gunzip config-2.6.26-1-686.gz
ss4200:/usr/src# mv config-2.6.26-1-686 .config
ss4200:/usr/src# cd
ss4200:/usr/src/linux-source-2.6.26# cd linux-source-2.6.26
ss4200:/usr/src/linux-source-2.6.26# mv ../.config .
ss4200:/usr/src/linux-source-2.6.26# make oldconfig
Answer all questions with yes
apply the patch from here. It will hopefully be in the mainline kernel soon.
Brigtness control:
Load the i2c dme1737 smbus driver if not already loaded or built in.
# modprobe dme1737
# lsmod | grep dme
dme1737 39501 0
hwmon_vid 3082 1 dme1737
hwmon 1936 2 coretemp,dme1737
i2c_core 23284 2 dme1737,i2c_i801
# cd /sys/bus/i2c/drivers/dme1737/0-002e/
# chmod o+w pwm5
# echo 10 > pwm5
# sleep 5
# echo 255 > pwm5
You'll see the lights get dim then bright again. These pwm outputs are
normally used for fans, but I guess they commandeered it to control the
LEDs in this case.
