Are you suggesting that it also covers fan speed control? Or do you mean that ACPI could do the fan speed control all in software based on the PECI input and e.g. a GPIO pin for fan control? BTW, I found that Maxim is doing chips to convert PECI signal to regular I2C: http://eetimes.eu/products/analog/198900334 -- Jean Delvare
