Convert JSON naming schema in Ember

I have an application where I retrieve JSON data from a server. Unfortunately the JSON data is formatted as such:

"Product_Group" : [
        {
            "Product_Group_ID" : "396xx",
            "Product_Group_SEO_Copy" : "Not Included in JSON",
            "Product_Group_Title" : "Some awesome Title",
            "Products" : [
                {
                    "On_Sale_Date" : "04\/28\/09 00:00:00.000",
                    "ISBN" : "97800617737xx",    
                    "Title" : "A Disgraceful Affair",
//rest of the it follows

Ember throws errors when trying to use Capitalized JSON objects in a template. Specifically the Uncaught TypeError: Cannot read property 'unchain' of undefined error. This is related to this issue noted on the Github Ember site.

My question, how can I convert all the titles from the server into camelCase? I don't have access to the server to change things on that end, so it will have to be client side. I've looked into the DS.RESTSerializer but I don't understand it enough to know if that is what I should be using.
