Today is a sad day for me... I stopped being lazy just to find out my camera has firmware 1.00b. Tested today's pre alpha anyway, and nothing. Camera just turns off, and won't turn back on until batteries are removed. I know there is at least 1 version of CHDK that work on firmwares with a different letter (my old camera, SD1000), but I don't think I should keep my hopes up, right?
I don't know anything about porting, and until I graduate in December, I won't even try to learn. Maybe by then there will be an easier way to extract the firmware other than by blinking.
In any case, keep it up
