I have some routines for those that run on the II:

http://alfter.us/files/onewire.1.0.bxy

I wrote them to use 1-Wire devices, but iButtons use the same protocol IIRC. 
An ASCII schematic of a simple circuit to connect to the game port is
included, but I'm guessing that you'll have something comparable on the card
you're building.
