I'd just like to report that I am having the same issue. I also have a Thinkpad x61, Core2. I just upgraded to Lucid a few hours ago. I tried disabling a core and saw the same problem. As Flávio wrote, I would have expected that to significantly reduce the number of wakeups. If I can be of any help in debugging this let me know.
