Have you, as a developer, been near xf86-video-ati recently?

I do not want another driver in there, especially now that we have 
libpciaccess. For instance, and this is a rather trivial one to solve, 
our driver can be loaded on its own.

We're still discussing how to solve this, but this is all kind of 
academic when we still don't have the documentation and aren't even 
talking about this documentation yet. Let's get the current stuff all 
resolved first.

The last thing we want to do though is pull an NIH, we are not into 
uselessly wasting time here.
