I would say the open source drivers work better on older hardware than 
the proprietary ati drivers... As others have pointed out the newer 
cards arn't fully supported by the open source driver.

I'm using the radeon driver included with X (x.org) in Core 3, and I get 
~2600fps(from glxgears...) off my Radeon9100Pro 128MB AGP card (AMD 
Athlon 2800+ and 512MB)
