Hi
Just a notice .. I can successfully run CF under Oracle Virtualbox 4.0.6 r7.
You just need to enable the 3D accelleration in the virtual machine settings, and then in the Guest OS, set the Display Adapter to 'Virtualbox Graphics Adapter' and NOT the 'VGA Adapter', then Shut down the Vistual Machine and Restart it.
After installing the Freelancer, and Crossfire, Start FL, and it will complain about a 3D card and shut down. Restart the Vistual machine again at this point, and after that, FL plays well without any problems.
Kind regards
