At least this is a really easy thing for them to add.
I wonder how localization should work here. One does not want to add
the description of the thermal zone in all possibly supported languages
into BIOS ROM.
Pre-defining 10 different areas:
0 Processor
1 Memory
2 Disk
3 Graphics card
4 ...
10 Others
and then returning an integer value sounds more sane.
If Len or Bob say it makes sense to come up with or add something which
we can tell the vendors to use and which may find its way to a later Spec
version...
After first being excited that HP provided a sane description of a thermal
zone, I think it's not worth adding this right now (or is it?).

PS: Forgot to add lm-sensors list, adding them now.
