This is definitely a kernel issue. I ran powertop with the latest Lucid kernel (2.6.32) and for comparison the last Karmic kernel (2.6.31) and under the Karmic kernel the number of wakeups from a standard desktop with no apps open is HALVED (!!!) from 220 down to 100. I am switching back to the Karmic kernel until they fix this.
