Torsten, Perhaps it would be easier for you to be added to the cern-kicad group. I suspect the GAL stuff was brought into the the tree because of convenience. (This was what you were working for right?) As for myself, I do not foresee me needing to commit anytime soon to GAL. I have a number of patches to look over and work to do on python for windows, fp lib table dialog perhaps.
