Oh, don't worry.
I've already coded a small fan controller daemon working around the problem
and driving the fan to run at the minimum speed sufficient to keep the CPU
cool enough. Anyone interested can look here:
http://svn.ferrara.linux.it/view/just4fan
or check it out from the subversion repository:
svn checkout http://svn.ferrara.linux.it/just4fan
In fact, now I run the system with it87 always loaded... it's soooo quiet!
Now that I'm used to this silence I can't live without it: I can't stand the
fan screaming anymore! I think for I won't move away from -mm until this
single feature makes it into vanilla :)

I'm sorry I don't know. How I could check?
Thanks again
