Just for the reference, I collected CPU detection from various branches.

6.4
  Cores per package: 4
FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs

7.3
  Cores per package: 4
FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs

8.1-rc
FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs
FreeBSD/SMP: 1 package(s) x 8 core(s)

Indeed, looks like a regression.
