Anyone here know anything about it?


I doubt enough to give you any useful pointers, but I do know it is significantly different than FreeBSD's driver model. I briefly considered trying to port a PCMCIA WiFi driver from FreeBSD to OS X a couple years back and researched enough to know it wasn't going to be a trivial recompile (Apple pushes C++ rather than C for driver development for starters). Apple's IO Kit webpage is probably as good a place as any to start.
