Perhaps Linux kernel wrongly detects type of = hardware, I don't know. I just have a PC with an LCD monitor. P.S. By the way, when I use the default mobile kernel without needed CONFIG_s = I have several more division by zero since PowerTOP uses default value of 0 to = lot's of variables. But since that CONFIG_s are required to run PowerTOP I have not reported it.
