Then _iff_ you get a /proc/acpi/fan and /proc/acpi/processor structure you can echo values to the particular files to both turn on/off fans and modify processor states (don't know them offhand - rules for processor control are given in the ACPI documentation, but for fan control check the acpi-devel list archives). Patches, some documentation and mailing lists are available from http://acpi.sourceforge.net/ Strictly, with working ACPI you shouldn't have to do anything - trip points are defined which will both modify processor states and the fan - but there are an awful lot of broken ACPI BIOSes out there that will work with Windows but don't conform to the ACPI spec.
