[1] You can try the maintainer's kernel Git tree and an older version?
[2] You might check OpenWrt's Git tree (checkout an older revision)?
[3] Check latest v3.4.y kernel from Ubuntu kernel team (UKT)?
Unfortunately, I haven't found the Git repository for
v3.4.109-quantal release.
You might ask on IRC or via mailing-list.
