Bugs 6729 and 7122 on the acpi-support bugzilla seem related, as does bug 72360 on Launchpad:

The problem with some HP laptops appears to have been the firmware, and the fan being reported as always on (or some incorrect signal like that). My BIOS is from September 2006 and I see the Lenovo website has an updated BIOS from 28 February 2007. Unfortunately the IBM website is inaccessible at the moment, so I can't test their update - will post here when I have tried that out.
