It looks like this isn't the only thing necessary if you use the OID. As make_private_key actually needs to call the
ECDH_PrivateKey constructor, this needs to be added to make load_key
function properly. Attached is a patch if you decide to go the OID route. Works on 1.10.1 and latest mtn sources.
