Hi, did somebody the HW Sensor on the 12" PowerBook (6,1) got to work ? 'ioreg -blsx' under OSX shows you an Analog Device 103x Chipset with two sensors. (located on the GPU Topside and CPU Bottomside). There´s only the ADM1032 supported by the LM90 driver ? I´ll give lmsensors 2.8.1 a try. practical experience would be appreciated. ;) TIA.
