You don't mention whether you're using the NAND or NOR version of uboot. 
 If you used the NOR version (Aux then Power) then the changes wouldn't 
be saved because it is the failsafe bootloader. If you used the NAND 
version (Power then Aux) then it should have saved. The commands look 
right from memory, assuming your uboot is recent enough to support 
ext2load, but I may have missed something.
