In that case could you post cat /proc/acpi/processor/CPU?/* ?
Perhaps we're losing ACPI C2/C3 state power saving, and checking the busmaster activity indicators there would be useful, too.
Oh, in this context maybe it's actually a problem of a misbehaving driver? An active USB mouse is known to distort ACPI power saving, causing reduced notebook battery operation length (due to busmaster activity preventing ACPI idling, I think). Now what if some certain driver actually caused permanent busmaster activity...?
