FWIW:
It's already indicated during boot for my fairly old Athlon64:

CPU: AMD Athlon(tm) 64 Processor 3000+ (1809.28-MHz K8-class CPU)
  Origin = "AuthenticAMD"  Id = 0x20ff0  Stepping = 0
  Features=0x78bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2>
  Features2=0x1<SSE3>
  ^^^^^^^^^^^^^^^^^^^
  AMD Features=0xe2500800<SYSCALL,NX,MMX+,FFXSR,LM,3DNow!+,3DNow!>
  AMD Features2=0x1<LAHF>
