I've written a cramfs reader for grub, to use on the DOC, and grub works
great on a DOC. Although the grub code is a bit ugly, and there are a
few gotchas, writing a module is pretty straight forward. That being
said, writing a module to load files of a journaled fs (jffs2), is a bit
more time consuming, but as I understand yaffs is greatly optimized
towards NAND (as apposed to NOR) flash layout and lends itself to easy
reading (same sized blocks, no compression iirc).

If I were you, I'd use grub.
