Pointers for understanding vfs/buffer/filesystem architecture

I've very interested in learning about FreeBSD's implementation of 
vfs/buffer cache/fs archicture.  I've read through mckusick@'s chapter 
in the Design and Implmentation of FreeBSD book, and I've read the UNIX 
Filesystems book cover to cover.

What I'd like to see/read/understand, is how FreeBSD in particular is 
put together in this regard, and then I'd like to go about writing a 
very very simple filesystem as a learning excercise.

Can anyone give me some pointers?  Would anyone be willing to guide me 
along in my quest by answering questions (off list if preferred, or on 
list), etc?

Thanks in advance for the hints/input!
