For what it's worth, I found this:
http://cvs.sourceforge.net/viewcvs.py/xoops/modules/xphpbbi/
I'd sift through it for ya but I'm soooo tired... I'm hoping maybe it's enough info for DonXoop to help you, or something...
Or you could go to www.bbpixel.com & ask Koudanshi, but I don't think he's around much these days. Seems it's his module.
Hope this helps.
