In the mean time, there's still DNG4PS2, which can convert RAW to DNG
http://code.google.com/p/dng4ps2/Unfortunately it does not support iZoom out of the box. However, by comparing data in the CHDK source
the iZoom appears to have the same sensor as ixus50, ixus55 and S2IS; you might be able to get the program to work
by creating a profile for it based on one of the above cams ...
I can't be sure though, haven't used DNG4PS2 for over a year (my cams all support internal RAW->DNG ...)
hope that helps,
wim
edit: OK, refreshed my memory on the program a bit, couldn't create new profile, but try this:
1. put your raw CRW file(s) in a separate folder (without the corresponding JPG)
2. start DNG4PS2 and browse to the folder
3. click Settings... and go to the "Camera Types" tab
4. Select one of the cams available in the "2672 x 1968" drop down
5. Once you get it to convert, try which cam setting gives the best results
