Station without power would start to tumble. Makes docking much harder. This actually happened with Salyut 7: the station died on orbit, no electrical or anything. The pilot of the rescue Soyuz matched its spin to dock manually. Effected emergency repairs while wearing fur-lined winter clothing. It must not have been tumbling too badly. Seems like once you have significant motion in more than one axis it'd be pretty hard to match up. At that point, you probably have to grab and despin, or something. Or dock really really fast and hope your docking mechanism holds up to the stress.
