You may want to check out some anthropological accounts in Africa and SE Asia for stories of natural unassisted births. I remember reading a book called Nisa many years ago and she tells of how she just had her babies and kept working http://www.amazon.com/Nisa-Life-Words-Kung-Woman/dp/0674004329/ref=sr_1_1?ie=UTF8&qid=1294706231&sr=8-1
I am not sure it will have much valuable info but at least it gives you a direction to move towards in terms of research.
Lastly one of my religious studies professors did a book on home birthing in N.America and there were a lot of references in her book to other cultural practices, her book is http://www.amazon.com/Blessed-Events-Religion-Birth-America/dp/0691087989/ref=sr_1_1?ie=UTF8&s=books&qid=1294706332&sr=1-1 so you may want to find this book and look at her references.
