[solved]macbook pro backlight problems

installed arch yesterday and finally got around to installing everything else as well today. I thought my problem was pretty simple i didnt have backlight control using the keyboard keys on my macbook pro 5,5. i followed the wiki and installed pommed and nvidia-bl and made the changes that the wiki has, but nothing. i have looked at many other options none work for me
i can run the following command in super user in gnome

 echo 256 > /sys/class/backlight_nvidia_backlight/brightness 

i have add and tried both suggestions that are in the wiki to pommed build function

find . -name "*" -exec sed -i 's/mbp_backlight/nvidia_backlight/' '{}' \; 

and

find . -name "*" -exec sed -i 's/nvidia_backlight/apple_backlight/' '{}' \; 

neither work.
i have also added pommed and nvidia-bl to the end  of my daemons rc.conf

DAEMONS=(syslog-ng  dbus networkmanager crond pommed nvidia_bl)

anyone have a clue has how to get it working

*EDIT*

i have added the following line Option "RegistryDwords" "EnableBrightnessControl=1" to  my /etc/X11/xorg.conf  under the section "Device" as this.

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    Option "NoLogo" "True"
    Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
