I had similar problem with my machine recently (it is Averatec 4150H) and after walking through the ASL, discovered that _TMP method in thermal zone object always returns same value which was stored away during ACPI initialization. I would suggest you check if 'sysctl hw.acpi.thermal.tzX.temperature' returns something reasonable (or at least changes with machine warming up perceptibly) and if it does not investigate conditional statement you have in _TMP method of the thermal zone object -- at first look it seams to return stored value at least along one of the branches. Please, keep in mind that I by no means claim good knowledge of ACPI and/or ASL and just share suggestion that worked for me.
