Hi, I have the same problem on kernel 3.2.0 (actually I have the same problem with all kernels I tried since reporting the issue the first time). I'm almost sure this is related to several Debian bugs open for upower: #606414, #596721 and #619343. Is it possible that the high cpu problem with upowerd is caused just to the log size increasing too much when the laptop is left on for a long time? In my laptop upowerd starts using a lot of cpu only when I leave it on overnight.
