I know its not where you are trying to go, but with a simple & cheap Arduino clone, you could read the ultrasonic sensor, convert distance to a pulse width modulated 5V signal and feed that via the USB port on the camera to be read by a CHDK script.
I have compiled another table of values. They are attached this time. As expected, the voltage vs value is linear.All that remains for me to do is to find out how fast I can read the values (maybe fast enough to capture lightning with an LDR?) then I guess I need to write some scripts and make some stuff to make use of it.
Not sure if this adds much, but a quick trawl through the Ixus 60/65 diagram reveals the following signal names and some sense of their meanings.

0xc0900046:0x00e0 < ccd temp0xc0900048:0x010a < optical temp0xc090004a:0x00d7 < battery temp......edit:I think 0xc0900044 is related to battery voltage. ~0x351 at 4.2 volts (external power), ~0x2d9 at 3.66 volts (battery, rec mode)
Any idea of where to start looking for those test points? Would the Analogue Devices chip handle these points as well as the CCD?
How is the _GetAdChValue function used? (google search turned up nothing) And does it have any advantage over the peek function?
