I'm running a rather out of date stable/9 on that one.  4.5 months to go.

On my Lenovo X200, in 2008 :)

Yours clearly oesn't have a TZ1.  We saw an HP laptop of some sort here 
recently that had 5 thermal zones, with TZ2 being the CPU/s temperature.

Every model's BIOS / ACPI is different.  Some will expose CPU, GPU, HDD 
and other hot things, perhaps with controllable fans.  Some hide them ..
