Sony Vaio VGN-FW21J: Brightness not changing

[SilverXXX]

I cant find anything to solve this problem (seems like no one has this laptop with linux on it).
All i could find was some old topic about sony-acpi, but in other topic i read it is now deprecated in favor of sony_laptop.
Yet i cant use brightness control in any way.
Anyone knows how i can solve this?

I've found the problem. The sony-laptop module still not support FW series laptop. A patch is alredy on trial.
