Non AES-NI code is removed from Optiminer's code. NiceHash's Hodlminer support non AES-NI CPUs. https://github.com/nicehash/hodlminer-wolf/releases

Hash rate without AES-NI support is very slow. I have Intel Core2 Extreme QX9650 and I get only 37 - 40 h/s. Here are some benchmark results http://hodlcoin.oo.fi:8080/cpus/CPU_vs_Hash_rate.xhtml .
