If I turn off DNG saving I do get RAW files. Maybe this is how it is supposed to work?
Yes.

Upon playing around with bracketing some more, I've found that Tv bracketing doesn't work with the custom timer set to multiple shots. It only works with regular continuous mode with the shutter button held down.
I have not played with bracketing much so I'm not sure how its supposed to work,  but this does not sound like something related to the 1.01C port - more a CHDK general thing.

I have done a lot of bracketing on an a480 with CHDK. I can use the custom timer, and it is consider the "right" way to do HDR stacks these days. The custom timer replaced many scripts.

Some of you might find this interesting.

Here is an HDR made with jpgs.

Here is the same basic scene with the same hdr processing settings but done with dngs.

The jpegs look better. The fish eye effect of the actual lens with no correction is pretty interesting though
with the DNGs.

Compared to the DNGs my a480 spits out, the ones from the sd980 seem to have more dynamic range available in them, and less noise.

The colors are magically awful in the straight RAWs. Everything is sort of puke green.

Thanks - learned something new tonight. I didn't even know my camera (SD940) had a "custom timer". It was kind of hard to find but knowing it was somewhere,  I got it.  Now to play HDR stack.

These are even more striking when compared to the jpgs you posted earlier in this forum.

There is a little bit of blurring in the HDRs because my hand is shaking while I hold down the shutter button.

The DNGs appear quite blurred compared to the jpeg. There is obvious camera movement between the shots, but in the jpegs they appear quite distinct. Canon jpegs generally have sharpening to counteract the mud from their noise reduction, but seems like something else might be going on.

The DNG is a bit warmer, but it's pretty close for a first cut color calibration.

That's down to whatever software you are using to display/manipulate the CHDK raw. The image data is identical to what is used in DNG (except for badpixel removal) CHDK raw doesn't have *any* metadata, so without additional information, programs that load it have to take a wild guess at the colors.
Don't forget what the H stands for.

I can't seem to get any of the old bracketing scripts to work.

More HDR Experiments

These are done in photoshop and are much more natural than my previous HDRs. I did a custom lens correction on the dngs. I think it looks better than what the camera does internally on the jpegs.

The dng based one looks more like reality to me.
