It would be nice to find out what part of the cleanup isn't happening right. Do you know at what point that "fatal error" occurs? Is it during probe? Can you post a short patch that will simulate the same effect? I will spend some time this week redoing the bugfix and cleanup parts of the as424b-as426b patches, without the bus glue changes. Maybe that will make a difference.
