Haven't read it either, but I'd assume the brother that was lost is Grey Wind, seeing as how he is dead. Summer/Bran have had similar thoughts and the lost brother (to go along with the lost sister) referred to the dead.

Well, I think you're making things needlessly complicated with that. The wights brought back through the Wall "came alive" at night. Remember that the Wildlings were always far less afraid of wights in the daytime. It was almost assuredly nighttime that reanimated them, not some un-named, un-seen, un-hinted third party that climbed the Wall near Castle Black the same day the Rangers brought back the bodies. I think we're getting real close to a "keep it simple" situation with that one. What is the most likely explanation there, really?
Personal opinion: The Wall is not a barrier against magic. It is a magical barrier against the Others and their ilk. Coldhands could not cross the Wall (said explicitly in SoS, BTW) because he has been touched/tainted by them in some way. Jon's separation from Ghost when he left him North of the Wall had less to do with having the Wall between them and more to do with the conscious decision to separate from his protector.
