I've seen it too. Looks like it is the bug. Have you noticed the priority 
they set it? LOW. :-(

I've tried Ubuntu Maveric, which runs 2.6.35 kernel and did not notice a 
problem.

Well, my BIOS manages fans as it is supposed.  The problem is that, in my 
taste, it is supposed (by design probably ?) to cook a laptop sooner then 
I would see it happen. :-) 

With i8krellm I always kept the CPU temperature below 48 degrees C. True 
- fans run a lot. But again, fan is a cheap part.
