(1) When a browser supports SSL 2, its SSL 2-only suites are shown only on the very first connection to this site. To see the suites, close all browser windows, then open this exact page directly. Don't refresh.
(2) Cannot be used for Forward Secrecy because they require DSA keys, which are effectively limited to 1024 bits.
