I started off with the same position as you, Henrique,
but Rui and Sujith don't see it that way.
Of course this is software, we can always change it --
particularly since there will be a very small list
of users for the new I/F, and we happen to know them:-)

The ACPI 3.0 thermal model requires quite a bit of sophistication from
the system designer and BIOS writer.
Based on the quality of system designs and BIOS code we see
in the industry, I think it is way over the head of 99% of the industry.

That said, if a system does come out that supports the ACPI 3.0 Thermal Model
and they want to ship Linux on it, we can look into it then.

cheers,
