I'll just add that there are two ways to reconcile DBpedia and Freebase
and they don't ~quite~ give the same answers.
(1) you can use the /type/object/key with /wikipedia/(en|de...) and
match that up with the dbpedia identifier, or
(2) you can use the numeric "en_id", "de_id" and match that up with the
number from dbpedia
Note you can generate a linkage file for (1) based entirely on the quad
dump, but to do (2) you need the page id's from DBpedia.
I've tried both of these and decided to use (2) based on a very superficial
analysis for Ookaboo. All I really know is that the results from (1) and
(2) aren't quite the same.

Here you go:
http://dbpedia.hg.sourceforge.net/hgweb/dbpedia/extraction_framework/file/dump/scripts/src/main/scala/org/dbpedia/extraction/scripts/CreateFreebaseLinks.scala
The script currently only looks for wikipedia/en links, but it's
trivial to change that to another language (and very simple to add a
parameter for the language).
The script needs the DBpedia datasets Labels, Redirects and
DisambiguationLinks.
