With completely linear history, you can probably use grafts and add df2d1a798e85c75b9abbfd22fe06ff651a8fa9dd as a parent of your original, initial commit. Afterwards, running dcommit should just work. (I've never tried this, though).

That will probably force you to discard your git-only history in SVN or have you duplicate history, neither is what you want. If it's not too late; I recommend you start over with the above instructions.
