Description : userspace interface to control the core voltage of processors
Linux Processor Hardware Control is a patch for the Linux kernel that
provides a userspace interface to control the core voltage of a computer
processor(s).
The main use of this interface is to lower the core voltage of a
laptop's CPU ("undervolt"). The goal is to reduce the laptop's
temperature so the cooling fan can safely run at a slower speed.
Another goal of undervolting is to reduce the power consumption of a
laptop and thus extend its battery lifetime.
Linux-PHC also adds additional built-in frequency/voltage tables to the
Linux kernel for some Pentium-M CPU models. This is particularly useful
for laptops with broken ACPI that can't use the speedstep-centrino
cpufreq driver at all.
Linux-PHC currently only supports the Intel Pentium-M class of
processors. The Intel Centrino Core duo/solo processors are also
supported but with some limitations.
The patch should work for kernels 2.6.15 - 2.6.21.

I'm searching for a sponsor -- if anyone is interested... :-)
