Not sure it is AMD specific.

  % sysctl vm.stats.pagequeue
  vm.stats.pagequeue.prime2: 5
  vm.stats.pagequeue.prime1: 9
  vm.stats.pagequeue.cachenways: 0
  vm.stats.pagequeue.cachesize: 0
  vm.stats.pagequeue.page_colors: 32

The CPU is:
  CPU: Intel(R) Pentium(R) M processor 1.80GHz (1794.19-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0x6d6  Stepping = 6
  Features=0xafe9f9bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,TM,PBE>
