I do have this navigation bar enabled in Opera, but I wouldn't call it implemented very well. It's a dozen buttons with fixed labels (Opera doesn't even read title attribute), and most of them are disabled most of the time. 

Home/Index/Contents buttons have different functions on different pages, e.g. on php.net 'Index' goes up a level, and 'Up' relation is not used. Docbook uses 'Up', but not 'Index', and puts table of contents under 'Home'. HTML5 draft uses 'Index' for table of contents. HTML4 spec has an old-school book-like index page, but does not use rel=index for it. 

Because these link relations are available sporadically, and they're not clear and dependable when available, I don't remember last time when I actually used them.

The only link relation that I find really useful in Opera is rel=next (which is hooked up to "fast forward" button).
