[gpm] About GPU speed handling in g-p-m

[benjamin canou <bookeldor gmail com>]

  Hi,

I think it may be interesting for g-p-m to handle GPU speed.
After having discussed a bit about this with Richard, I launch this
thread to start collecting informations and thinking about an
implementation, as well as performing tests to verify the real impact on
power consumption.

Here are some links for NVIDIA cards:

There is the nvclock tool:
http://www.linuxhardware.org/nvclock/
There is also a thing called CoolBits for the "official" support, there
are some hints in the FAQ:
