[Bug 563815] [NEW] [STAGING] Critical temperature reached (100 C), shutting down. throttling too little, too late.

[Wolfgang Kufner]

Public bug reported:

Under heavy use the Acer Extensa 5630Z always overheats and shuts down. I noticed this in lucid, but karmic shows the same principal problem.
The main culprit seems to be that the clock frequency is reduced too little and too late. 
It should reduce clock frequency more/sooner to avoid the forced shutdowns.
