The closest thing I could find was mql-to-sql http://code.google.com/p/mql-to-sql/ -  I would use this but it looks like it requires a custom mapping and I'm really interested in the entire freebase corpus from the data dump.

There are a bunch of reasons that won't currently work, but my
favorite is MQL execution speed.  A wild guess is that the setup you
suggest could be 100x slower than Freebase.  Is that acceptable?

Why not throw the raw dump (not the per-type TSV dump) into your
favorite tuple store and use SPARQL?  It won't be as elegant as MQL,
but it'll do much of what you want.
