The last version of ACR (Adobe Camera Raw) that was released for Photoshop CS2 is version 3.7. Support for your camera was added prior to that version, but I didn't take the time to find out exactly when it was added. You need to download and install ACR 3.7. There is a link to the download near the top of the forum page, and on the download page there are complete instructions on how to install the updated plug-in. The plug-in must be installed in the precise folder/path that is described in the instructions or it will not work. And it must replace the older version that is there.
