Unfortunately, the generic ACPI driver does not permit much fan control. There are some board specific ACPI drivers, providing better support (eg ASUS and Thinkpad), but for the most part you either get no or very limited fan monitoring/control support. I don't know if generic support for ACPI based hardware monitoring can be improved. Since it might be useful to know, I am copying the ACPI maintainer and the ACPI mailing list. Maybe they can provide some additional information or pointers.
