I have written a script for Bridge that does deflickering and ramping of ACR settings for timelapse purposes.
You can get the script here:

Further dissucssions about this script have been going on over at the Magic Lantern forum here:

I thought I'd share it over here, as it has reached a pretty stable state and most of the bugs have been ironed out. Please hit me up with any questions or bugs.
