By certificate-based ciphersuites, do you mean TLS_RSA_WITH_*
ciphersuites from RFC 2246 specifically, or any ciphersuite that 
uses any kind of certificates?

(To me it looks like many of these arguments would also suggest
defining a separate EAP type code for e.g. ECC certificates
based on the RFC 4492 ciphersuites. I don't think that would
be a good idea...)
