Well, the BSDs definitely have drivers, but I find the BSD VFS layer
quite confusing to be honest ;).

Then there is http://elm-chan.org/fsw/ff/00index_e.html which from my
gut feeling has a compatible license (read: needs verification).

I'm sure with some extensive search one can find a workable driver. Or
for example Apple could just contribute theirs as BSD licensed.
