I don't agree this is necessarily bad. Arguably, "view cache" is a feature for power-users that know what they're doing.
Moving the cache link into that pop-up did simplify the user interface in the most common case, in which the user just wants to view the real link. It no longer has to be rendered for every result.
IMO it just takes some getting used to that the cache link has been moved. Or are you viewing pages from cache that regularly that the extra clicks/mouse moves are a problem?
