[ale] CPU question, dual core?

[jimpop at yahoo.com (Jim Popovitch)]

I lease a few servers from here and there.  A new one that I just got 
showed more than 1 CPU in the bootlog (WARNING: NR_CPUS limit of 1 
reached) so I installed an smb kernel and wallah, it boots and finds 2 
CPUs.  I run several virtual systems on this host, and the smb kernel 
seems to have doubled the system's capabilities and performance (from my 
10,000ft view).  However, hwdata shows the motherboard to be an Asus 
P4P800-VM (http://www.dealtime.com/xPF-Asustek_P4P800_VM) which is a 1 
cpu board. /proc/cpuinfo shows both CPUs as
   vendor_id       : GenuineIntel
   cpu family      : 15
   model           : 4
   model name      : Intel(R) Pentium(R) 4 CPU 3.00GHz

I believe this to be an Intel Hyper-Threading CPU, but I slept though 
discussions of those CPUs over the past few years.  So, is this a 
dual-core CPU?  Is an smb kernel the right kernel for such?
