I never understood why the speed depends on AC power (except to fake a long autonomy). It would be smarter if it scaled the speed based on CPU usage. It's what I did on my notebook (athlon 1.3G), and I'm happy to run it all the day at 500 MHz and not to hear its stupid CPU fan dancing every minute, and I too am happy to be able to compile a kernel in 3 minutes even on battery, when it would take 10 min at 500 MHz and eat the battery much more, since LCD and disk eat power during 7 more minutes.
Just my thought...
Cheers, Willy
