Yes, this works on my rv790 games get high and using vdpau/gl for video 
stays low (which is nice as the fan on my card is too noisy on high).

One thing which I guess 99.999% of people won't notice is that doing any 
thing with plain X + fluxbox (so no compositing) very briefly ramps up 
the speed.

As my fan is just audible on low but very quick to respond I can hear 
every time the screen gets updated eg. switching desktops, 
browsing+scrolling or switching tabs, even typing dmesg in an xterm 
which time shows as taking < 0.1 sec results in a fan change.
