Steve, I've updated Proj4js with the proj4 version of the stereographic projection and my test point now comes out at the correct location.
You can get the update at https://svn.codehaus.org/mapbuilder/cscs/trunk/proj4js/lib and use the file proj4js-compressed.js (or proj4js-combined.js if you want to debug what's going on inside). Compressed and combined versions of proj4js include all files required. Let me know if that works for you.
