Compare the options with those listed at the top here: http://www.lesswatts.org/projects/powertop/faq.php CONFIG_TIMER_STATS is probably what powertop needs. The others are intended to reduce power, and seem a good idea to enable anyway. (except that CONFIG_SND_AC97_POWER_SAVE may give problems on some systems: but that option can be switched on/off at runtime I think).
