Hi Robert,

As long as GeoServer knows what your native projection is (via .prj file,
geometry_columns entry, etc...) it will be able to reproject it to any other
coordinate system it supports. You can verify that the native crs has been
picked up on the layer page in the admin ui.

Past that all it takes is to set the srs and bbox parameters of a wms
request accordingly and geoserver will reproject. If you are unsure if your
openlayers map is configured properly i find it helps to install firebug to
see exactly what map request is being sent to the server.
