Unfortunately, at the moment we're much worse than fglrx. However, we're
slowly starting to develop power management features. Still, there's
quite some work to do to get competitive.

Not that we know. The docs tell us how we could disable GPU elements (if
little 3D power is needed), but I somehow doubt that this will actually
save us any power. More likely they will just not get any data anymore,
but still run at full speed.

On the other hand, any additional worker is very welcome :-)
