Dell D810 thermal problem ... still

[Rod Haper]

Is anyone else running FC4 on a Dell D810 laptop?  I'm still having 
problems with thermal shutdown at 40-41 deg C.  i8kmon (and my ears) 
confirms that the cooling fan is running at full speed.  If I boot 
KNOPPIX, I never have a thermal shutdown even when the temperature goes 
as high as 55 deg C for an extended period.  I have not been able to 
figure out what KNOPPIX (a Debian derivative) is doing different from 
FC4.  I've been struggling with this for over two weeks now and I'm not 
any closer to a solution.  I know Dell laptop BIOS and hardware sensors 
can be pretty kinky but this is reaching the point of desperation.  Does 
anybody have any ideas, suggestions and/or experience with this problem 
that can help me get it resolved?
