Ditto, a buddy got me looking into CHDK for my Canon but mine's an SD900. The raw image feature really caught my attention. Let me know if there's anything I can do to help (I know C for the most part, but I'm not really up on firmware or systems programming...)
i believe all you need to do is find the correct values out of the firmware to plug into the chdk souce code. if you know basic c your better off then all of us other sd900 users
someone linked me to these pages in regards to my [horrible] attempt at this:
