Are 1024 bytes of a bigger kernel image really a problem? And even, normally kernel images are compressed, and compressing 1024 zeros can be compressed very well. I think saving memory is more important than saving disk space. I know that most ARM device use flash disk, but also most ARM devices have limited RAM.
