I do agree with you, Andreas and other ppl on that this is expected behavior on ext2, and ext3 should be chosen over ext2 when such corruptions are under consideration.
However, mount -o sync won't fix the problem for ext2 either :) I sent a report last week about that ext2 doesn't actually sync writes even if an ext2 partition is mounted -o sync,dirsync. Andrew confirmed that ext2 has MS_SYNCHONOUS holes (and possibly O_SYNC holes).
check out http://www.uwsg.iu.edu/hypermail/linux/kernel/0503.0/1252.html or google "Junfeng mount sync".
