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!
