I'm sorry but I really don't understand why people are suggesting an unauthorised upload. If you supply a patch in an RT queue then your fix is available to anyone who wants it regardless of whether the maintainer applies it. It's not uncommon for example for Perl modules in Debian to be built from the official release with selected patches added.
If the maintainer has abandoned the distribution you either care enough to adopt it and continue maintenance or you don't. Uploading an unauthorised and unmaintained module really doesn't help anyone.
