Git-to-svn convert

Is there a reasonable way to convert a Git project to Subversion... Yeah, I know, blasphemy :-P... but I worked on a project in Git and my boss wants me to put it into Subversion.

git-svn looks to be the tool for this.. however I had some non-linear dev, which doesn't look like it'd commit (In the past I think I tried this and it failed to deal w/ a branch-and-merge...).

Example of what I mean...:

a - b -
 `c'

As to how to pull the repository into subversion.. how would I do that? git-svn init ?
