[lm-sensors] Intel QST support in lm-sensors

[Tim Boundy]

I've been reading through some old threads regarding support for Intel
QST in lm-sensors which have largely died out due to lack of
information from Intel or lack of functional kernel drivers etc. I've
just had a go at getting the Intel QST SDK up and running on my
machine and managed to get the sample StatTest application working.
The SDK was written against an old heci driver, but there's a new mei
driver in the mainline kernel (/dev/mei) which required a minor patch
to the Intel QST SDK (see https://github.com/gigaplex/Intel_QST_SDK).

My machine is using an Intel DG965MQ motherboard, running Arch Linux
with kernel 3.2.5. Perhaps now is a good time for a lm-sensors
developer to take another look at this?
