One of the linux kernel devs has an sl series with intel graphics, and fixed our brightness problems! I've tested this module, works pretty well. Try it, you'll like it. It also makes the other hotkeys work.
you'll have to compile it, install it, blacklist video, and u should be good.

ya, maybe we should send him a pizza. I'd pitch in a couple of bucks or so. I think the current plan is for its brightness control to be replaced in the future by proper patch to video.c in acpi by Zhang Rui (kernel bugzilla bug 12249), but compiling and installing this manually is good enough for me for now. I'm just happy it gets addressed.
Viva open source!

I've got a Lenovo SL 300 running on Ubuntu 8.10. I was compile this driver got an .ko-file.
When I load this module manualy like this:
works just fine.
But the module didn't load up automaticly at boot time. I try to follow this: http://www.cyberciti.biz/tips/compiling-linux-kernel-module.html, but didn't works.
Could you help me to fix this?

I just wrote it into my /etc/modules, and I blacklisted video in /etc/modprobe.d/blacklist
gary@gary-laptop:~$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded

First of all thanks your quick reply garytr23, it's very usefull! Now I know why didn't work my solution: I didn't blacklisted any module.
Otherwise someone at ubuntu.hu (forum of the hungarian ubuntu community) suggest this: http://gianlucamagalotti.wordpress.com/2009/02/16/lenovo-thinkpad-sl-series-hotkeys/ . This is a complete solution for this kernel module problem.
