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.
