Activity Monitor dock icon only shows one processor?

I did check the preferences before posting – there is no option to show two bars instead of one.

Floating CPU Window is not really what I'm after...I like the out-of-your-way aspect of the dock icon. I'm wondering if this is a Leopard-specific change for dual-processor machines, or just for the eight-cores? From my POV it's a reduction in functionality for no good reason. I like to see how the load compares on my two processors.

Yes, thanks for the confirmation. I did some googling and found more people with eight-cores who could not view more than one bar in the dock icon.

I understand that showing eight bars in the icon might've been unreadable, but I would have preferred that they show two bars for the dual processors, instead of leaving us with one bar. I'll have to look into some alternate utilities, but it's a shame Apple decided to regress functionality on their top-end machines.
