battd, as far as I know, is just middleware for an actual battery read daemon. And again, as far as I know, the issue isn't with battd but rather the actual root battery daemon not sending battery information to battd to show in the actual UI without very specific circumstances that TheKit has had trouble recreating. Again take what I say with a grain of salt, I don't have much experience with OMAP devices and porting because the PowerVR graphics that usually accompany them are a nightmare to work with.
