I'm not sure.  I agree we want the new-format resize inode change
(there was a patch for this by Takashi Sato posted to ext2-devel)
and the endianness changes, but I don't know if the latter is in
CVS yet or not.

I believe the latest resize2fs can already do the ioctls necessary
to run online resizing, but it can't do the prepare step.
