The patch has zero impact on a running system, only suspend/resume behavior is affected. Precondition: Suspend computer with keyboard backlight brightness greater than zero. Before patch: On resume, the backlight stays off. After patch: On resume, the backlight is set to the brightness prior to suspend. There is one side-effect of the patch: the accelerometer no longer re-calibrates on resume, but keeps the calibration from before suspend. I consider this a good change, but it is after all a change.
