You've probably got HTT disabled by sysctl rather than in the BIOS.  In that 
case, top "sees" that your system claims to have 4 CPUs, but you're only going 
to schedule tasks on 2 of them.

Turning HTT off in the BIOS rather than via the sysctl would probably make 
top's view of your system more sensible...
