I have had this same problem ever since Gingerbread was first leaked. When I brought it up here, people acted like I just need to SBF and install again (like their's still worked!). I miss the visualizations too, but it's not a big deal. I have SBF back to froyo and re-installed GB recently, they're still not working.. ****, I even think Froyo visualizations weren't working anymore too..
