I tried the above and it worked, if you have the time, try it to and let me know how it goes! :)
Well, perhaps you can backup your uboot, but it seems that you can't write it back this way:
# mtd write u-boot.bin mtd0
Could not open mtd device: mtd0
Can't open device for writing!
[edit]
You can, but it's not as trivial, so it requires some hoop jumping to get it done.
# mtd write u-boot-env.bin u-boot-env
Unlocking u-boot-env ...
Writing from u-boot-env.bin to u-boot-env ...
# mtd write u-boot.bin u-boot
Unlocking u-boot ...
Writing from u-boot.bin to u-boot ...
