You can safely ignore these warnings, it is simply fdisk complaining that the 
sectors do not line up on the DOS defined CHS notation.  The sectors are 
aligned for 2kbyte erase blocks (hence the recommendation of bs=2048, but you 
are safe without using it) that are defined in flash.  This allows us to use 
the same partition table on both the SD card and NAND flash as well as easily 
change between the two.

Using `fdisk -cu` from a host PC will stop these messages, just make sure to 
keep everything aligned on 2048 byte boundaries.
