[LinuxBIOS] dual core disable?

[Greg Johnson]

Disabling dual core on our s2891 boards with Opteron 270's doesn't seem
to work properly.  When I boot with dual core disabled, I am getting two
cores on one socket enabled and none on the other socket.  Here's 
/proc/cpuinfo with dual core disabled:

It also performs like it's using both cores on one socket.  Any
thoughts?

Thanks,
