I put two files at http://www.minet.uni-jena.de/~joergs/ img-broken and img-working. In the last image, img-working, I can access all files, especially "test/broken fürß". The first image, img-broken, is the image after running e2fsck -Df on img-working. So you can test if one of these images work on x86, especially if the file "test/broken fürß" is accessable.
