commit d6b9880d709ab5732242cf3fedfdc26853049f9b
Author: Stefan Tauner <stefan.tauner at gmx.at>

    Add support for Intel D945GNT
    
    This is based on the patch from Beata dalHagen, see
    http://serialice.com/pipermail/serialice/2012-May/000372.html
    This version has only been compile tested.
    It seems like we should use kconfig more, but i don't know this
    stuff good enough yet. Still better than copying the whole file :)
