Thanks for the speedy reply, Steven.
I already had the new iPod DLLs, but I overwrote the existing with the files from the link you provided. The files matched what was there, but after a restart of MB, the iPod is now showing up correctly and syncing upon MB launch. I don't know if we were experiencing sunspots or something along those lines, but if it happens again tomorrow, I'll be sure to let you know.
Thanks again.
