Short searching in git log show this patch http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8eb2dfac41c71701bb741f496f0cb7b7e4a3c3f6 "It turns out that LRW has never worked properly on big endian." and maybe also http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fd4609a8e00a867303783ade62d67953fb72adc8 So I think since 2.6.29-rc6 it "work properly" and in previous kernel all ciphers in LRW mode on big-endian arch produce wrong output. Can you try to apply this simple patch(es) to old kernel and then check if it works in new one?
