The Ubuntu 8.04 you are running is Hardy, a different and older release than this bug is discussing (9.04, Jaunty).
My thinkpad idles at nearly 50C... in windows... in ubuntu etc. Thermal shutdown on Core2 Duo's is over 100C. It does not sound like you are experiencing the issue discussed here and frankly it doesn't sound to me like you have a thermal issue at all.
