Ooooooo, a trap! I should have saw it coming.
I'm not saying your incorrect but you may wish to check your list of references. Just a quick perusal of your list I see a number of Pelegians and, in some cases, officially deemed heretics (Chrysostom). I don't think this is an objective crowd as you may feel.
But I'm off now. I'll try to look into this matter soon.
The point is that this particular Greek construct, though invisible in the English translation, has been widely-known among authors of many POVs, including Calvinists, for twenty centuries. Ergo, there's absolutely no creedence for believing that the "faith" is the "gift of God" spoken of in this passage.
But in any case, don't take my word for it--go check it out for yourself.
