Cipher suites which provide perfect forward secrecy are those which use a Diffie-Hellman key exchanged, signed by the server -- but the server key may be of type RSA. Consider the TLS standard: there are two cipher suites which use AES with a 256-bit key, SHA-1 for integrity check, and a RSA server key:
Only the latter provides perfect forward secrecy. In the former, the key exchange is done by encrypting a random value with the RSA server keys, something which can be unraveled later on by an attacker who could steal a copy of the server private key.
Information provided by Opera does not seem to be sufficient to distinguish between those two cipher suites.
