Just use git-svn - since the history is quite large, and you're only
really interested in recent stuff, you probably want to limit the
clone to those revisions since 3.2.8, i.e. something like

  git svn clone -r <rev>:HEAD http://www.virtualbox.org/svn/vbox/trunk vbox.git

(where <rev> is whatever was tagged as 3.2.8 or some other place you
want to start).
