Thermal management implementation is in our queue. We'll create
policy manager for ACPI subsystems including thermal (Active, Passive
cooling etc.). Of course any help would be welcome :-)

Currently we don't have any means to control fan device (except for
the machine specific tools).

You could find `3.10 Thermal Management' for overview and
`12 THERMAL MANAGEMENT' for detail in ACPI 2.0 spec. Also
`7.1 Declaring a Power Resource Object' and `10.6 Fan Device'
may help you.
