Hi Jeremy,
I have a similar issue with an Sun Fire X2200:
CPU: Dual-Core AMD Opteron(tm) Processor 2218 (2613.45-MHz K8-class CPU)
  Origin=3D"AuthenticAMD"  Id=3D0x40f13  Family=3D0xf  Model=3D0x41  =
Stepping=3D3
  =
Features=3D0x178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE=
,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT>
  Features2=3D0x2001<SSE3,CX16>
  AMD =
Features=3D0xea500800<SYSCALL,NX,MMX+,FFXSR,RDTSCP,LM,3DNow!+,3DNow!>
  AMD Features2=3D0x1f<LAHF,CMP,SVM,ExtAPIC,CR8>
  SVM: NAsids=3D64

and setting debug.cpufreq.verbose=3D=E2=80=9C1"
does not make a difference (ran diff with and without it)
you can get it at:
	ftp://ftp.cs.huji.ac.il/users/danny/freebsd/dmesg.boot =
<ftp://ftp.cs.huji.ac.il/users/danny/freebsd/dmesg.boot>

cheers,
