(For iMX35 at least): The barebox image doesn't contain anything in the first 
1K apart from an unconditional branch to the reset vector (at 2K offset). This 
branch is not necessary for internal booting, because the app entry point is 
specified in the flash header information.

sudo dd if=barebox.bin of=/dev/sde bs=512 seek=2 skip=2

similarly for the env and kernel...

sudo dd if=barebox_default_env of=/dev/sde bs=512 seek=512
sudo dd if=${KERNEL_LOC}/arch/arm/boot/uImage of=/dev/sde bs=512 seek=1536
sync && sync


Make sure that your boot pins are set to boot from SD!! 

Cheers,
Marc
