Diy Serial Cable Help?

I'm looking to make a cable that would let my 5500 connect to a SparkFun Tri-Axis accelerometer.

Information on the accelerometer can be had here: http://www.sparkfun.com/commerce/product_i...products_id=248

I know that the Zaurus doesn't provide enough power over the serial connection, but I think there are solutions to it (either running some of the serial wires to a power source or directly powering the board).

The wiki page on making your own serial cable looks a tad old, and the section on using the Zaurus as a DTE remains unverified. I'm not too experienced with crafting my own serial cables, so any advice that people have would be appreciated. I currently have in my possession:

Two (2) Zaurus PDA serial port connectors
One (1) Serial cable I am willing to tear up
A soldering iron
Time and inclination :-)

Does anybody have any advice on the best way to go about doing this? What color cables go to what pins? Forgive me if these are newbie questions.
