The only way which would make sense to a certain degree is to resurrect
the SmartMedia Format driver, which bitrots in the old MTD CVS. It is
designed to allow FAT on NAND FLASH, but I have no idea whats the
current status of that code is.

A parition does not transform NAND into a block device. You need to use
the block device driver of MTD. Be warned that you will wear out your
FLASH in foreseable time and data loss on powerfail is guaranteed by
Is there any real good reason why you want to use FAT on a FLASH?
