MacOS X special file device drivers?
I love my Mac, and I love that it is UNIX underneath its sexy dress. But it's BSD, basically, and that means it's not Linux, and Linux is where I cut my teeth kernel hacking. I can write a device driver in Linux (both 2.4 and 2.6 kernel), and I have done. But I'm all at sea when it comes to doing the same for MacOS X. Where do I start? What is the Mac equivalent of the O'Reilly book Linux Device Drivers?
I ask specifically because I would love there to be a BSD equivalent of the /dev/full special file device driver (reads return ASCII zero, seeks always work and, crucially, writes always return ENOSPC, which is POSIX errno code for 'sorry, ran out of room'.) It is very useful for testing code that writes to backing store (and if your code doesn't write to backing store at some point it's probably either really lame or broken.)
I want major/minor 1/7 on my Mac to do the right thing. How?
Look, I understand the Mac software development model. I have written Mac applications since 1984, which it is pretty obvious neither of you have. I want Darwin dev docs, not vague handwaving.

Linux is open source, Mac is not. All software (including system software) for Mac is bought. You can only talk to the guys who hacked Macintosh, like the Voodoo team. (What about applying for a job at Apple?...)
