The linux code is not of help, since you are not allowed to copy it into the FreeBSD code. Regarding the FreeBSD side of things: as far as I know, the sound system infrastructure needs to be extended to know about more than two channels per output device. But I better let other people which know more about the internals of the sound system than me comment in this.
