I don't think there's a point to using cpufreqd with the latest Intel
processors. The ondemand governor is supposedly the best configuration
for processor power saving.

Actually, at least for the 9 cell, Lenovo's data sheet said 9.4 hours
for Vista, I believe, while I can get up to ~14-15 (wifi off, lowest
brightness, reading PDFs). Even with Linux, I can get up to ~10 hours.
