do Phenoms not support powernow? I am a bit puzzled by the differnce with two X2 boards I have around here : FreeBSD 7.1-PRERELEASE #0: Tue Dec 2 20:09:28 ... CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ (2992.52-MHz K8-class CPU) Origin = "AuthenticAMD" Id = 0x40f33 Stepping = 3 Features=0x178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT> Features2=0x2001<SSE3,CX16> AMD Features=0xea500800<SYSCALL,NX,MMX+,FFXSR,RDTSCP,LM,3DNow!+,3DNow!> AMD Features2=0x1f<LAHF,CMP,SVM,ExtAPIC,CR8> Cores per package: 2 ... cpu0: <ACPI CPU> on acpi0 powernow0: <PowerNow!
