Yes. That and the accompanying code which they released with a BSD license. Their documentation has too many holes to be used alone (no AtomBIOS details, missing registers, etc.).
Now here is what I meant when I mentioned the Genesi certification with ATI. Genesi used to have contacts at ATI who would know the right people to talk to. However, since ATI was acquired by AMD, the right people tend to move around, leave for other jobs etc.
Just to clarify, the driver requires minimum Amiga OS 4.x. With several people still working on Amiga OS 3.x stuff, I think that it's worth being specific about requirements.
Do you think a driver could be developed for OS3.x ?
