“Got” vs. “Gotten”

The Straight Dope makes me feel better about my Yankee grammar:

“Gotten” is actually the older form of the word, dating back to at least the fifteenth century. The King James translation of the Bible, published in 1611, prefers “gotten” to “got,” but it was written in a self-consciously grand, archaic style. Shakespeare, working at the same time, seems to have preferred “got,” which by then had become the colloquial style. The “got” vs. “gotten” battle raged throughout the 1600s, the colonists taking “gotten” with them to America, where it flourished, while the stay-at-homes eventually came down on the side of “got.”
