A free font with OldStyle figures as default

I'm having some troubles with the Calluna font by exljbris in combination with the LaTeX typesetting software. For the technical details I'm trying to get some support at stackexchange, so I won't bother you with it, but to make my problem reproducible for other people I need a font with the following properties:

  • Available for free, without registration
  • Provides both oldstyle and lining figures
  • Has oldstyle figures as default numerals, so the character called one is an oldstyle figure
