My rheostat work as follows:
Down is 0v and up is 28v (or something very close to those values)
When the rheostat is at 0v, the AMX240 and AXP340 buttons are full bright. When the rheostat is turned slightly up and a little bit of voltage is provided, the buttons go full dim and my instrument lights connected to the same rheostat are full dim. As I turn the rheostat up, the buttons get brighter and the instrument lights get brighter.
I set my IFD540s to use only the photocell for the time being since I just didn't have time to get it working properly with the rheostat.
Here is a poor quality iPhone video I took tonight where you can kind of see what happens. The units are full bright, the rheostat is off. I then turn up the rheostat slowly and you can see it dims completely then gets brighter as the rheostat goes up.
I think it may be time to upgrade from an iPhone 4...
EDIT: I just saw Scott's post above and my installation works exactly as he describes above.
