I think it might be that powertop is on crack here. I see that at the top of powertop's overview all the time (with only a few terminals open), but on powertop-1 it never shows up. Here's a snapshot of both, taken at the same time (on precise):
powertop: Usage Events/s Category Description 2316 rpm Device Laptop fan 100.0% Device Audio codec hwC0D0: Conexant 16.3 ms/s 85.9 Process /usr/bin/X :0 -auth /var/run/lightdm/root/:0 vt7 -novtswitch -background 16.9 ms/s 59.5 Process compiz
