It just sets it while ide-cd actually checks for the capability. The drive is not reporting it while it can so ide-cd needs blacklist entry for it. Now that idecd has blacklist entry, all should be fine. Eh... I'm not sure whether we need to update sr to follow what ide-cd is doing or not. Thanks. -- tejun
