This post is related/continues my previous one. I have written a small sample that shows how to call the GetNativeSystemInfo and IsProcessorFeaturePresent functions on Windows Phone 8 devices using a C++ runtime component. For the moment I cannot think of a really good use for calling these functions because there are only two processors on the devices currently available. You could detect which of the two processors the device has and also its features.
Here is a screenshot of the sample running on my Nokia Lumia 920:
