Ben, this note to point to you that the upstream tools repo has a change-set commited that implements the fallback to read-only devmap loading. It could help with your open bugzillas. Now, as Alasdair agreed to permit loading RW devmap for multipath maps over RO devices (*), I don't know if it's really needed ... but it can't hurt.
