Wow you work fast. ;-)

(I think you mean thermal sensors)
A solution in search of a problem. I can say this because I helped define
it. :)
The machines that care about manageability (servers) appear to be entirely
disjoint from the ones that have thermal zones (and, servers use IPMI),
therefore thermal chip contention doesn't happen. And, Metolious required a
fair amount of AML code.

No, I mean voltage sensors. They are on same smbus as thermal sensors,
yet their are not normally accessible using ACPI. I can talk to smbus
controller directly, but acpi may decide to read temperature while I'm
reading voltage, leading to armagedon.
How is that solved?

Well, I thought that "simple" specs looks reasonable, I did not look
at "advanced" metolious. But it seemed sane (*).

I have seen desktop machine that can control CPU fan (altrough it is
slow/fast not on/off) and has thermal zone. It would be nice to be
able to check voltages in a safe way...

Talking about IPMI - is there anyone working on SMIC interface to IPMI
driver written by Corey Minyard? (http://home.attbi.com/~minyard). He
isn't working on it personally as he told me, because he doesn't have such
HW.
I've just downloaded specification from intel and can start working on it
after I finish my other projects, but I am asking firstly, to avoid
implementing it if someone is currently doing it.
