This is weird.
Overriding read works for me. In the FireBug console:
>>> var f = new OpenLayers.Format.GeoJSON({read: function(str) {
>>> console.log(str); }});
>>> f.read("foo");
foo
Likewise the following patch to the feature-grid.html example works for me:
diff --git examples/feature-grid.js examples/feature-grid.js

Patching the feature-grid.html example has made me realize that
there's something wrong in the above code. The read method is
obviously set in the prototype, so OpenLayers.Format.JSON.read should
be OpenLayers.Format.JSON.prototype.read, and likewise for
Format.GeoJSON.
