Hello ...

 Is someone working on linux support for the new fan control unit built in
 recent pmac64 ? Or has further details ?

You mean the latest G5s ? not yet, as soon as I get the hardware hopefully

It looks like apple released the source (opendarwin) for the new cooling
system: PowerMac7_3_CPUCoolingCtrlLoop.cpp (AppleMacRISC4PE-125.2.2)!

Is there an easy way to use this code to get the cooling system working
in linux ?

Possibly, though it's the high level control loop, it lacks the low
level driver, I'll have to figure that one out in different ways. I'm
waiting for one of these models (already ordered), so I'll work on that
as soon as I get it.
