Kernels 2.6.35 and newer will set superblock fields that will result
in those messages. They're not error messages per se; it's just a
notification that there was an file system error in the past that
hasn't been fixed yet. In your case, it *has* been fixed, but you
don't have a new enough version of e2fsprogs so that it clears the
relevant parts of the superblock.
The debian packages of e2fsprogs version 1.41.14-1 in experimental, or
1.41.12-4 in unstable, has the necessary new code in e2fsck. I'm
working on getting the patch pushed to Debian obsolete^H^H^H^H^H^H^H
stable; hopefully that will happen in the next week or two.
