This is caused by the 3.3.1 kernel code looking for different file names
than 3.3.0. This situation can be fixed by either changing the
filenames or changing the kernel code.
Up to now I've been doing the latter but this may not be the best
approach as the internal STE repo use the notation currently sought
after by the 3.3.1 kernel.
