powertop makes various recommendations that are only useful in very
specific circumstances. Disabling polling in hal saves you a small (and
probably not useful in the real world) amount of power, but is required
to get to the number of wakeups per second that Arjan was aiming for. I 
haven't been able to measure any difference in power consumption on a 
typical system.
