    x86_64: 64-bit index register should be used.
    
    Looks like qemu does not accept 32-bit index register, while the
    real boxs and virtualbox accept 32-bit index regiter.
    
    However, according to AMD <<24593--Rev. 3.17--June 2010>> Page 25,
    64-bit index register should be used to create effective address.
