[lm-sensors] Chipset not supported

Hello, I'm having temperature issues with my chipset, but it's not on 
the support list. I don't know how to help add things, and it sait to 
mail it out to the mailing list, so here it is, I am using a laptop with 
the Mobile Intel PM965 chipset. I'd help make it work, if someone told 
me what I need, or someone can do it themselves. I'm willing to help 
anyway I can. Thank you :D

Most laptops don't have usable sensors (other than the ACPI thermal
zones and CPU integrated thermal sensors). Anyway we can't say anything
about your specific system without seeing the complete output of the
latest version of sensors-detect:
  http://dl.lm-sensors.org/lm-sensors/files/

Also please check if the BIOS display voltage or fan speed values. If
it doesn't (as is the case of most laptops) then there's probably no
monitoring chip on this system so nothing we can do.

I had a brief look into the PM965 datasheet (http://www.intel.com/Assets/PDF/datasheet/316273.pdf).
Apparently it has internal temperature sensors. It also supports Intel MEI,
which afaik can be accessed to read the chip (and possibly CPU) temperatures.
There is a MEI driver in staging, but I don't have any idea how to use it.
