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.
