ISTR that tz0 is some kind of a sham on X60 or, at least, on 1709-73U
that I own. It does not implement _PSV, _PSL, _TC1, _TC2 or _TSP and is
useless from passive cooling standpoint. Its _TMP method returns 128C
under some conditions _regardless of measured temperature_. Did you
actually see any attempts at passive cooling when you overrode _PSV in
tz0?
