I'm sorry.  Is there any particular section that was confusing?  What 
could I explain better?

Is this a 2.4 or a 2.6 kernel?

Can you send the current values of all your current settings by running 
something like:

   head /proc/sys/dev/sensors/adt7463*/*

which will work on 2.4.  If you're using 2.6, you'll need to do 
something similar in /sys
