I suppose this means the card is just that slow?

It means the time is spent for the actual rendering, not just for the clears. Maybe you can narrow it down further, e.g. by sprinkling glFinish() calls across more places.

You might get better performance out of the card with a current 3.5-rc kernel thanks to better tiling setup, but it is a lower end card, so I wouldn't expect any miracles. :)
