Correct.  NOR U-Boot only supports SD booting off FAT+EXT3, for example -
if the kernel isn't in a FAT/VFAT partition it barfs.  (though
interestingly it should be possible to boot the same distro off SD with
either of two kernels - Qi looking for /boot/uImage.bin and NOR UBoot
looking for a uImage file in the root of a FAT partition)
