I have created a new cpu-miner 64bit and I achieved about 22% more khs/sec .
This version is based on cpu-miner-1.2c by ig0tik3d, and plus uses AES-NI/AVX instructions from an other library, so it's usable with this list of Intel Processors:
http://ark.intel.com/search/advanced/?AESTech=true
and with these series by AMD:
AMD Bulldozer-based processors
AMD Piledriver-based processors.
AMD Jaguar-based processors.
AMD Kaveri-based processors.
I'll release it today, but it's in alpha stage and needs testing because I tried it just with a Sandy Bridge i5-2400 from a friend.
I have not cpus to mine, so bounties for my time will are very appreciated.
Let me know if you are interested.

Oh thanks, you are right! I dont ask for donations now or later, I'd want to say that I'll appreciate that later if it works for who use that, because I cant mine . Anyway, thanks to you, I forked ur project, but if u like, we can collaborate
