Clockworkmod Recovery is a wonderful tool, but doing anything for the Xoom through Rom Manager is fraught with danger for the unsuspecting. I'm surprised this doesn't happen more often.That's one of the only two ways to brick it. I would stop by the irc channel, but I think you may have actually bricked it.
