I finally managed to migrate some things to Subversion from Bazaar. This does not yet include Gammu related things (Gammu, python-gammu and Wammu), because they are more tricky to migrate.
However all Debian packaging now can be handled using svn-buildpackage, which makes things a bit easier. Also smaller projects like Ukolovnik, polld and dictionary converter have been migrated.
You can see list of repositories at http://svn.cihar.com/, where is also link to web based browser.
Please note that repositories might change in future, because everything is not yet completely settled down.
