If you say yes here you get access to the hardware monitoring
functions of the National Semiconductor PC87427 Super-I/O chip.
The chip has two distinct logical devices, one for fan speed
monitoring and control, and one for voltage and temperature
monitoring. Fan speed monitoring and control are supported, as
well as temperature monitoring. Voltages aren't supported yet.

This driver can also be built as a module. If so, the module
will be called pc87427.
