I wrote such a thing a few years ago for our news servers. I needed
direct access to a partition while still going through VFS so that
mmap() could be used.

See ftp://ftp.cistron.nl/pub/people/miquels/kernel/v2.2/rawfs-0.6.tar.gz

There's also a v2.3 version but I haven't tested that extensively yet,
and I still have some patches pending for it that I need to apply.

It might not be exactly what you need but it's a start.

Mike.
