Ah, Excellent!  I was confused because the dmesg from the Athlon MP
board that John Baldwin posted about had the only the FXSR flag but
not the SSE flag set.  Interestingly, its the same Id and stepping:

CPU: AMD Athlon(tm) Processor (1194.68-MHz 686-class CPU)
  Origin = "AuthenticAMD"  Id = 0x661  Stepping = 1 
Features=0x183fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR>
  AMD Features=0xc0440000<<b18>,AMIE,DSP,3DNow!>


I guess it must have been an early rev or something.  

Cheers,

Drew
