This happened a couple of weeks ago, but I only found out about it recently. Nuke released the full kit-n-kaboodle of USBGecko as open-source at http://code.google.com/p/usbgecko/ — this includes not only the source code for the latest WiiRd and GeckoOS under GPL, but the full schematics and VHDL files for the USBGecko itself under the BSD license. Bravo!
