Driver for some ASUS desktop motherboard extras.

Though it is named after overclocking tool for ASUS motherboards,
it is not capable to change clock ratio or CPU core voltage.

This driver exports Templature, Power output voltage, Fan RPM under
dev.acpi_aiboost.0.*.

Descriptions for these values are set to sysctl describe, which can be
get by sysctl -d.
