Do you set the sphericalMercator option to true when creating the
google layers? You need that option if you want to have vector
geometries on top of google layers. Also the coordinates of your GML
data must be in EPSG:900913. If not you'll need to reprojected your
data, either at the server side or at the client side. Note that OL
can natively do 4326 to 900913 reprojections (and vice-versa), but if
your data doesn't use 4326 you will need proj4js in addition to
OpenLayers; see the numerous posts on the subject.
