Opera on the 9500 seems to be sending a blank Cookie2: header along with all its requests, and as such livejournal isn't working at all.
This seems to be a problem with Opera, too. As soon as you set a cookie in Opera, it will return a Cookie: and a Cookie2: header along with every request it makes to that server. And to add to that, even when you use Set-Cookie2:, Opera still returns the cookie you set in a Cookie header, not a Cookie2 header.
Brokenness on all sides, really.
