Nevermind, I finally got my passive cooling working.
Here's the diff against my acpidump -dt:

I don't know if the values of _TC1, _TC2 and TSP are meaningful, but it
seems to work for me, having a _PSV value of 65C.
Any suggestions on those values are welcome.

This seems to keep my laptop's temperature around 65C.
Thanks again,
