It's interesting that not only has this fix gone into the kernel, it is also mentioned in the changelog for the just-released ALSA 1.0.23.

    - ALSA: hda: Fix 0 dB offset for Lenovo Thinkpad models using AD1981
    BugLink: https://launchpad.net/bugs/551606
    The OR's hardware distorts at PCM 100% because it does not correspond to
    0 dB. Fix this in patch_ad1981() for all models using the Thinkpad
    quirk.
