Looks like links that have been recoloured by this feature should
be reported to JS as though their colour has not changed.
What about size of bounding box? Position of other elements? There are a
lot of possible style changes you need to hide. Doable, but this code will
have a lot of bugs and exploits. So current choice: all or nothing - looks
like a good compromise...

The Link Status extension (mentioned in an update at http://whattheinternetknowsaboutyou.com/docs/solutions.html) restores a bit of the lost functionality, by adding the time since the link was last visited to the status bar when you hover over the link. It also has on its preferences a checkbox to toggle layout.css.visited_links_enabled if you are using Firefox 3.5.
