Hey, this is great stuff.  It wish we could have talked about it a bit
before it was commited.. Most of ffs_rawread.c is fairly generic.  Do you
think you could make a vfs_direct.c or similar and move the generic bits
in there?  It looks like you could keep the ffs specific bits to a minimum
and then leave the rest as helper functions.

Do you have an application that is using this immediately?
