You might be able to just skip the board you referenced above and get the breakout boards for the individual components and just hook them up directly through I2C to the Crio.

Coming from a hobbyist not and EE and someone with a little but not a ton of hardware programming experience this is just a thought.
Actually, I've been working a lot with I2C as of recent, and I know for a fact that you can use the I2C for communicating with the Magnetometer as well as transferring data to another slave. However, it seems like too much of a work-around to solder a wire directly to the pins to make it work, etc.

And you're right, they are using the same micro as the Duemillanove. I have one and I'm an avid Arduino user. Actually, keep your eyes open in the coming season... My team (107) might just be using a bunch of them, if I get things my way.
