I get the same OpenDNS "guide" page with ads on it for non-existing domains too, as well as when a site is temporarily not responding.

that's weird. maybe i have a grandfathered account? i just tried a bunch of different typos and all of them resulted in firefox page, not opendns. i also don't see any settings to turn it on/off. I however found a references from a couple of years ago, one of the OpenDNS people commenting on a blog entry saying that they can turn it off if you ask for it. I don't remember asking myself though.
