Ok your right this kills the razr...wouldn't even boot. The answer really needs to be in the device tree I suppose.

or possibly add a NULL check for mLightsService

That thought occurred to me but i wasn't sure of the best location. Show me where to put it and I can try it out.

Maybe like this?

                if (mKeyboardLight != NULL) { // new check for NULL
                    if (now > mLastUserActivityTime + KEYBOARD_ON_DURATION) {  
                        mKeyboardLight.setBrightness(0);  
                    } else if (mContext.getResources().getConfiguration().hardKeyboardHidden != Configuration.HARDKEYBOARDHIDDEN_YES){  
                        mKeyboardLight.setBrightness(mDisplayPowerRequest.screenBrightness);  
                        nextTimeout = now + KEYBOARD_ON_DURATION;  
                    } else if (mContext.getResources().getConfiguration().hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES){  
                        mKeyboardLight.setBrightness(0);  
                    }
                } // end of the NULL check block

Tried what you suggested and a few variations. None worked. I will keep trying when I have some time.

Check this out LiquidSmooth-Old/android_frameworks_base@a51ac16

You can remove the liblight hack in the d4 tree and keyboard light will go out when not used/closed.
