It's not just EAP channel binding that you need, but EAP cryptographic binding. Remember: what EAP calls "channel binding" is very different from the meaning of "channel binding" used elsewhere (RFC5056 describes the difference in terminology); EAP cryptographic binding is closer to the more generic (IMO) meaning of channel binding.
