To be honest, unless you've flashed a lot of mods, reflashing the rom without wiping data is pretty quick. Your only other option, really, is a nandroid restore (you *did* make a backup first, right

), and that will take longer than just reflashing the rom.
OR, if you happen to like any of the mods here that affect the notification bar, you can flash one, as some of them bring the notification back to stock (e.g. the circle battery mod with the normal notification bar):
