I have confirmed the same problem with a simple gdal_translate - the geotransform values are lost.

the geotransform was being written out but with a coordinate system of "PIXEL". However, on read, GDAL and I think PCI tools ignore the georeferencing transform for PIXEL. So instead, if there is no coordinate system but there is a non-default transformation I write "METER" as the coordinate system. This seems to resolve the issue.

Fixed in trunk (r18109), 1.6 (r18110) and 1.6-esri (r18111).
