I got it from sourceforge now and it did indeed "do" something:

sid:~# /opt/e2fsprogs/sbin/fsck.ext4 -v /dev/md0
e2fsck 1.41.5 (23-Apr-2009)
/dev/md0 contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
i_file_acl_hi for inode 12042 (/lost+found/#12042) is 64578, should be zero. Clear? yes
i_file_acl_hi for inode 12207 (/lost+found/#12207) is 5, should be zero Clear? yes
i_file_acl_hi for inode 12249 (/lost+found/#12249) is 5, should be zero.Clear? yes
i_file_acl_hi for inode 12090 (/t/#12090) is 5932, should be zero. Clear? yes

...but the "Input/output error" persist :-\

Maybe the repair with 1.41.{3,4} before did something wrong and I should 
use 1.41.5 from the beginning? This issue is somewhat reproducible (given 
the fs holds enough files), so I could start over, corrupt the fs again 
and let e2fsprogs-1.41.5 do the whole job.
