Comment 17 for bug 387620

Asif: I see no reason to believe Ubuntu isn't using throtling in you system. What's not using however is the option to override trip_points - that's the reason for the <setting not supported> and <polling disabled> results in thermal zone. I've learnt that unfortunately the option to override trip points were removed from the kernel because it was unsafe (the cpu had to poll the temperate and in the event of a failure you could fry it...).
