There might be something useful in 

At one point, there were two competing FAT filesystem implementations.
This is just a FAT12 implementation though so was the other one was
picked and merged.  The FAT implementation Eugeny was part of the 
team for includes a block device driver interface and caching support.

The FAT12 was by Camilo Alejandro Arboleda <carboleda at angelcomsa.com>
includes a floppy device driver but it precedes the libblock code so
would have to be modified to use that interface.

I would be very happy to merge floppy disk support along with 
some READMEs.
