I don’t think what you’re attempting to do is possible, but I don’t know. Not knowing is probably why no one has stepped up to try to help. As far as I know, there is nothing during save process that will tell you what options page is being submitted.
I suppose that you could use an acd/save_post action. In your filer you could check to see if the post_id value is ‘options’ and if it is then check to see if one of the fields of a particular options page has been updated and if it has then do the redirect.
