Oliver,
Yes. I am working on this. I will send you a patch soon; probably by the end of this week. See if they work for you.
Currently my thought is to make cardbus-bridge resource allocation nice-to-have, which means it will be attempted to allocate. But if in case of failures, we wont go the full length of releasing other resources to satisfy this resource.
