Kewl! You guys are awesome!

Duh, would have thought they might make that available pretty easily,
but good to know you figured it out. I previously had been using nvclock
to read it, but I think going through nouveau is nicer (and I know it's
pretty hot most of the time as nouveau is not that good on power
management as well, good things take time, after all).
Keep up the good work!
