Fedora doesn't really care about the radeonhd driver. We may well even
remove it at some point soon. The ati driver is the one you should use
on Fedora, that's why it's the default.

You do not get 3D acceleration out of the box on that card, r600 3D
acceleration is too early to be enabled by default. If you want to try
it out, install the mesa-dri-drivers-experimental package.

For the slow 2D performance - _how_ slow is it, really? gnome-terminal
has never been much of a speed demon. Does it get any faster if you boot
with 'nomodeset' as a kernel parameter?
