You should try looking harder:

CPU: AMD-K7(tm) Processor (499.03-MHz 686-class CPU)
  Origin = "AuthenticAMD"  Id = 0x612  Stepping = 2
  Features=0x81f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT
,MMX>
  AMD Features=0xc0400000<<b22>,<b30>,3DNow!>
...
Pentium Pro MTRR support enabled

I suggest you go read the documentation before you come back.  No 
offense, just a caution to check more carefully first.
