Just like there is a "Favorite" star next to the address line in Firefox (pressing it calls up a box to add the address as a favorite), there could be an option to display presence of several microformats as such small small icons.
Otherwise, perhaps something like a bar of microformats presentce indicator lights between the address bar and the google searchbox could also allow to avoide intrusive second toolbar line.
