There's earlier discussion on the list about some runaway Gnome activity which is keeping things busy...I haven't seen that isolated yet (so I'm taking a look).
poll-mode CPU is sampling based, adjusting frequencies based on utilization over the sampling interval. event-mode (the default) is more responsive...it filters out transient CPU activity to a degree, but evidently not enough to work around all this X activity...
