the following example will make the seed 500MB into a 2 Gb partition

FILENAME=/mnt/base-us/deb.5gb.ext3
dd if=/dev/zero of=$FILENAME bs=1M count=1500 oflag=append conv=notrunc
e2fsck -f $FILENAME
resize2fs $FILENAME


(You can choose ANY size just swap the 1500 for however many MB you want ADDED)
SEE THIS POST FOR A KINDLE DD THAT SUPPORTS THE RIGHT OPTIONS, (or do it on your PC)

That seems an efficient solution.

Alternately as pointed out by Icantbebothered:
FILENAME=/mnt/base-us/deb.5gb.ext3
dd if=/dev/zero bs=1M count=512 >> $FILENAME
e2fsck -f $FILENAME
resize2fs $FILENAME

that last command is to be used on a NON MOUNTED system only...
