Auto ISO on s110

I've installed CHDK on my s110. Everything appears to work except Auto ISO. It worked briefly last night but then fails to go beyond ISO972 or Canon's reported ISO1600 as per my settings on the canon, despite my setting the max at ISO2000.

Can't help much with the CHDK Auto ISO as I don't use it. I have a few questions/suggestions though:
- How do your Auto ISO related CHDK settings look like?
- Your camera does have a few options that can affect the dynamic range of photos (DR correction, Shadow correct, ...). Are any of those enabled?
- Do various shooting modes (P, Av, Tv, ...) have an influence on the issue?
- Does it matter if you shoot in single shot mode or one of the continuous modes? Is Servo AF enabled?
