@Ploaj: Right, 4 bits per color, not pixel. Derp.
@supersmashball: Try this program I made: https://dl.dropboxusercontent.com/u/3181.../PVREx.zip
For now it just assumes the pixel format is the same as the file you gave me, and spits out an error message otherwise. You can just click and drag any .pvr files into the executable and it'll extract them to an "output" folder. Let me know if any files give you trouble, and I'll take a look at them.
