Correct archaic CPU model "model" field for Intel CPUs.
The old "model" values caused two known problems:
    
    - Skype crashes on a winxp guest if model < 6, due to syscall vs.
      sysenter confusion.
    
    - 32 bit windows doesn't enable MSI support if model < 13.
    
After consulting with Intel the following recommendations were
received which more accurately represent shipped silicon.
