Its been a while since I messed with it, and I finally got my fan problem
solved by replacing the computer with one that had a working ACPI bytecode.
What The problem is that the ACPI code for your machine was probably compiled
with the Microsoft compiler, which gives a clean compile on errors that would
be caught by the Intel compiler. You can dump this bytecode to source and try
to recompile it with the Intel compiler. That will likely show you what's
broken. If you're lucky you may be able to recode to fix the errors and then
load your new bytecode rather than the broken one that shipped with your
The best place to persue this question further is the freebsd-acpi mail-list.
If Nate Lawson can't help you out, you're probably stuck with a noisy
machine. At least you can be confident that it won't overheat. :)
