I know this is cosmetic, but could we change this behavior and just
show one Tux on all systems?  As a software tester, this just looks
like a bug.  Alternatively, let's put labels under the Tux images
showing "CPU (N)", "CPU (N+1)", ....

This seems like a much better way to know the state of your CPUs:
