I can verify that it does not. I didn't think it would (being unpowered) but since I do sync my iPod to my 8887, I've had it attached and not seen the power-charging animation of the battery (or the lightning bolt graphic).
I have seen on a mac site somewhere (search these forums, I've posted the link before when discussing power taps) this firewire line CHARGER thing. It basically is a pass-through firewire connection (i.e. connects to computer, then ipod connects to it) and there's a power cord that goes either into a car adapter or an ac outlet (depending on config you get).
