I'd guess you would get a lot better history by importing Marcus' svn tree (as he has already done the job of manually pieceing together the shaky cvs development history up to the point of I don't recall when).
But maybe there isn't any good tool to first pull svn history into git and then continue from there pulling in additional history from cvs. (I'm afraid I've again forgotten that svn repository's location. :-)
Git's good, though.
