[Centos] CentOS-3.3

Thank you for the long awaited x86_64 port!

Looking through the RedHat pages concerning their EL releases, I find 
that the ES and WS versions claim to support only 2 CPUs while the AS 
version supports, well, more.  With the CentOS releases following the ES 
releases, can I assume that this too is limited to two CPUs?

Is this a kernel issue or something else?  Should I be thinking of 
loading a non-CentOS release on a quad Opteron box?

Thanks,

Bill
