I made a special version of Google Maps page for N810 from this user style. It requires that you put some code into userContent.css (or see below), but as it is genuine Maps page (maps.google.com), not embedded content, it's possible to use Street View feature, which is unaccessible from embedded maps. ... And it may be better to use the import method to apply this code: place gmaps.css in the same folder where userContent.css is, usually ~/.mozilla/microb/chrome/, and insert at the beginning of userContent.css "@import url('gmaps.css');" without quotes.
