I cannot see _TC1, _TC2 nor _TSP in your `acpidump -dt' output.
Further, there is no _PSV definition in anywhere, in the first place.
It seems to me that your ACPI BIOS doesn't support passive cooling at
all.

I suspect that you set hw.acpi.thermal.tz0._PSV manually.  Of cource,
it is insufficient to make passive cooling work with your ACPI BIOS,
and you need the definition of _TC1, _TC2 and _TSP as well.
If you define apropreate definition of them, passive cooling will
work.  But, we don't provide overriding the values of them.  Perhaps,
modifying your ASL (`acpidump -dt' output) to add the definitions of
_TC1, _TC2, _TSP and _PSV, and loading it from loader will make
passive cooling work.

Sincerely,
