I think that especially when we start thinking about CD, usability becomes a greater issue for accessibility. In my opinion a non-usable site (for generic users) cannot be very accessible for disabled. Usually the site is designed for some purpose and if no-one can achieve their goals does not help users with special needs at all. Ofcourse usability can be defined and measured in many ways so there might be some cases were I agree with you. For instance, it might be that users not relying on visual information might find an otherwise non-usable graphic site accessible. But I wouldn't call the site generally accessible (or usable) in that case. It would just be accessible for that user group, in that context for achieving certain goals.
