Compare the options with those listed at the top here:

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).
