which command to see dual Xeon 2.66 GHz cpu in action?

Hi;
	I have installed snapshots on dual Xeon 2.66GHz. Is there any command that I 
can use to see the dual-cpu and the Hyperthreading in action, especially with 
regards to the loads on each processor? Moreover, as a user of the bsd.mp 
kernel I would expect the usual `ps`, `top`, `systat` commands to return the 
CPU ID that each process is running on the system as well as the load of each 
CPU but they don't actually reflect that statistics of each CPU. Any comment 
on this..?

Regards,
TEH
