It working with setpci implies that you need a native backlight interface which unfortunately does not exist in i915 under KMS at the moment. There is discussion on exposing a native backlight interface so XRANDR can control such devices upstream but the details haven't been worked out and it probably wont go in until the 2.6.35 timeframe.

Is there a platform driver that can drive your backlight? hp-wmi doesn't support it?
