  * debian/rules: Install rules into /lib/udev/rules.d instead
  * debian/util-linux.dirs: Create new location, don't create old.
  * debian/util-linux.preinst: Remove the old rules if unmodified.

and kernel 2.6.28 which is there since last week of december

The only things remaining are e2fsprogs and ubiquity I guess.
