Not really, unfortunately. The CPU certainly runs slower, but the difference in power consumption between the fastest and slowest speeds seems to be quite small. The kernel was configured to use APM idle calls, but no ACPI stuff. I measured the time it took for the battery to go from 100% to 90% while reading the lkml mailing list with gnus, so the machine was mostly idle during the test. How much power savings can be expected in this situation? Is SpeedStep likely to give more power savings?
