I would concur.  I tried compiling FatFS, which I feel is the best low 
footprint FAT library out there, and it was 28K of 6502 code.

I would look to it as you code up ML, though, as I think the code is 
very nice.  I made a Long Filename variant of it called FatFS-LFN that 
we use in uIEC and sd2iec.
