[SOLVED]lenovo ideapad u350 backlight issue

Hi, as the thread title says i have an issue with the backlight on my lenovo ideapad u350.
/sys/class/backlight/  is empty so i cant use xbacklight.....
I allready added acpi_osi=linux and acpi_backlight=vendor to my menu.lst, but still /sys/class/backlight is empty....
but I can set the backlight with sudo setpci -s 00:02.0 F4.B=xx , does that mean i just dont have the right module loaded?
what do I need to do, to get the necesyary stuff in /sys/class/backlight so i can use xbacklight?
havent found anything with google or in forum/wiki besides people using setpci -s 00:02.0 F4.B=xx , or people having
backlight dimming working out of the box.

thank you very much that did the trick.
kernel.org is down so i had to edit the PKGBUILD, but now everything works.
