I've bisected v3.7 (good) to v3.8 (already bad) with your lsmod, and
using this script:
    #!/bin/bash
    set -e
    git clean -dX
    git clean -d
    make allmodconfig
    make LSMOD=/home/ymorin/r.pj.day.lsmod localmodconfig
    grep ATH9K .config

(and manually answering the few new questions), and it turned up the
following cset as the culprit:
    23c1d7f: wireless: allow Atheros card to not depend on ath.ko

Not sure where to go from there... :-/
