I have seen this problem between Suns and a Pyramid.
It seems that du works out the sizes using the st_blocks field of the stat
structure, but different system have different ideas about what constitutes
a "block". I have not managed to find any definitive answer to what a "block"
should be - If I remember correctly, Suns assume it to 512 fixed, always, but
other systems treat it as some property of the filesystem.
