AES-NI not detected with i7-980X

Hi List,

    I am trying to get gpg2 using AES-NI as I need to backup a LOT of data and would like the extra performance. I have an Intel i7-980X which does support AES-NI according to the cpuinfo (below) and according to Intel's website. I added a printf statement in rijndael.c to check to see if it was using the instructions and found out that AES-NI was not in the hardware capability flag.
    Any suggestions?
    Chris Adamson.
