My next guess is that perhaps the kernel you're using doesn't support process affinity? I'm not sure if that is possible, but it's a guess.
As for why cpu1 stats are 0, either you haven't switched cpu models yet or nothing has run on the second core (It's been idle). This is likely given that you haven't managed to run your benchmarks yet which would provide enough load to wake the second cpu.
