In my variant on bootldr, I use a small yaffs partition to house a linux zImage. This has a very rapid mount time and low ram footprint. This could be a way of lightening the initial ram burden if you are using yaffs-direct before booting an os.
If you are severely ram cramped and/or not booting an os then I guess you could split the nand up into small partitions and mount/unmount each one as needed. Its a bit clumsy but its an option.
