OK, that is very helpful. I should say that even without the profiles the images don't look bad and the contrast curves and exposure correction work, as do the focus peaks, so that a reasonable assessment of the image is perfectly possible without a camera profile, though the more profiles you have available the better.
As for creating profiles, one the CHDK data is amalgamated with the jpg header into a DNG file with 'DNG4PS' the camera model is in the EXIF data so that will not be a problem. I was about to ask about what images you would like when your additional bit arrived. Taking those shots should not be a problem, other than finding the time. However, colour target shots may be a little harder as those downloaded are only as good as the printer, or screen, and as my screen is set up better than my printer and has a bigger gamut, I was going to suggest screen shots might be the best option without the (quite considerable) expense of buying an accurate printed chart. If all that sounds reasonable I will put together a collection of images for you, though there is no great urgency for this.
