The fastest line between two points would probably be to run YAFFS Direct and 
create a "blockfile". Then write a "block driver" that you use to access this 
file as your FAT partition.

That would give you the wear levelling as well as provide you with YAFFS for 
system files (ie. non FAT ones). At least then if your FAT gets hosed, the 
system does not turn into a brick.

This would likely not be as fast (execution wise) as a custom-engineered block 
driver for FAT, but it should get you further down the road faster.
