This is *not* correct.

GoogleMercator doesn't exist -- it was a relic which was changed for
2.5. Information on the projection you will need to use is available at
http://trac.openlayers.org/wiki/SphericalMercator . You will set a
'sphericalMercator' option on your Google, Yahoo, or other layer to
'true', as per that wiki page.
