Yes, there is a BSD personality mode that offers (some) kernel services  
use BSD APIs.  This is so the userland works right and sees what it  
expects.  And so that BSD style sys utils like sysctl will work and  
stuff.  Still a layer on top of a totally different architecture.

Even if it was an old driver made for the first ever version of MacOS  
X, the driver level interfaces are much different so I don't see much  
how it would help you.

Mind you, I have not written a driver for OS X or FreeBSD, but the  
opposite question often comes up on some OS X forums/lists I read...
