Hello

I'm not sure I understand your problem. But if what you want is have
overlays over google maps you'll need to use SphericalMercator. See
some doc here <http://trac.openlayers.org/wiki/SphericalMercator> and
some example there
<http://www.openlayers.org/dev/examples/spherical-mercator.html>. Hope
this will help you do what you want.

Cheers,
