Ah, that's why. The partitioning is limited to cylinders, i.e. it rounds
down your partition a bit, here I get

/dev/loop0p1               1         130     1044193+  83  Linux

which is not exactly like linux' loop device size
   7        0    1048544 loop0

So you indeed need to give mke2fs the proper size by hand.
