This was working in 1.8, but it's not working in 2.x releases (so far). You may have heard of the update to "SIP API v2". Since we did this, Qt objects are converted to python objects to make it more natural to use for developers. Before that, you could just retrieve the existing valuemap and edit it in place, because when you called layer.valueMap(idx), you would receive a reference to the map QGIS internally works with. However, the new SIP API converts the map you receive to a native python dict and creates a copy of it. And if you edit this copy, QGIS doesn't realize, that there are changes. So, in short: If you use 1.8, just edit the map you get back. If you use 2.0, I don't think there is a possibility and there won't be one in 2.2. However, for 2.4 there will be an update which will make this possible again (with a new API).
