You need to enable CONFIG_CPU_FREQ, then powermac support for it (CPU_FREQ_PMAC64), then you can enable the windfarm driver for your machine (CONFIG_WINDFARM_PM81)
I did it, but still the fan stays on all the time once it starts. I think it stayed off a bit longer this time though, the X server had already started by the time the fan went on. I attached to this message the new dmesg, config and cpuinfo, just in case. Maybe these lines (inside dmesg.txt) have something to do with it, looks like the smu-i2c bus is registered a bit too late, or maybe its registration is triggered by windfarm ... I don't know. windfarm: SMU i2c bus 0x0 not found in device-tree ! i2c-dev: adapter [smu-i2c-00] registered as minor 7 SMU i2c bus 0 registered Should I be trying a modular version? You had mentioned that not all dependencies were right, that's why I compiled everything in. Eduardo.
