The opt-out page says you can opt out by blocking Googlebot in robots.txt (Yeah, right. Watch everybody rush to do that ), or add a <meta name="googlebot" content="noarchive"> tag to pages you don't want included (i.e. all of them). I already have <meta name="robots" content="noarchive"> on all my pages, which appears to be honoured for the SERPs so why does this need a Google specific tag?
