I first did the debugfs change, then created the ext3 journal with tune2fs,
then mounted the partition, then as you suggested
mkdir post.new
mv post/* post.new

mv: cannot stat `post/Badfenstert\374rumbau.doc': No such file or directory
mv: cannot stat `post/d-boxk\374ndigung2.doc': No such file or directory
and so on

Are you really sure that this is the same problem, because it only affects
filenames with umlauts (äöüßÄÖÜ in german), should a hash algorythm
problem not affect also filenames without them?
