I know this thread is a couple of weeks old now, but for the sake of posterity...and anyone who searches threads looking for this kind of info, I have a quick $.02 worth to add...
I don't know if this applies to Elements or not, but with Photoshop (such as CS2) if your camera isn't supported "out of the box", usually it's just a matter of downloading the latest Adobe Camera RAW file from their website. Basically the file is one of those ".8bi" files like the PS plugins...ya just copy the updated file to the Adobe Common directory (on a Windows machine, it's usually under Program Files). Since Elements is based on Photoshop, I would think it would be the same or similar process.
Adobe Camera RAW, at least when it comes to Photoshop, is the file that contains the actual camera profiles and such...and Adobe is usually pretty good about keeping it updated when new cameras come out.
One quick addendum for those interested... If you ever have to reinstall your Photoshop, say from cleaning your computer due to a virus or spyware or something, you will also have to reinstall the updated Camera RAW file as well as any time you uninstall Photoshop, the new file will be deleted, so keep a copy of it in a separate directory.
Again just a quick $02 worth!
