It should be available on the RPI site (as they originally made it) but the SMD version is only available here I think (the RPI folks only wanted one version)
OK, here are two new parts with the changes made. You folks will want the tht version, as it has both holes for .1in headers and pads to allow soldering the module to the top of the board. As well the holes for the USB connector are automatically drilled and the pcb silkscreen has the keepout areas specified. Schematic has the ground pins consolidated on a single ground pin at the bottom.
