There is a big difference and it has already be reported as a bug.

The current mke2fs creates (by default) filesystem with sparse
superblocks, which need a 2.2.x kernel to work. The mke2fs does notb
check the current running kernel neigther does it warn about this.

You can create the old stly fs by adding an option to mke2fs:

"mke2fs -s 0 -r 0" (should work)

More about this is in the manpage to mke2fs.

By the way, update your kernel why your at it. :)

May the Source be with you.
