I will try it first thing tomorrow. I also see:

dev.cpu.0.freq_levels: 1002/-1 939/-1 876/-1 814/-1 751/-1 688/-1 626/-1 563/-1 501/-1 438/-1 375/-1 313/-1 250/-1 187/-1 125/-1 62/-1

Shouldnt it show ~1800 as a level? This is the processor

CPU: AMD Sempron(tm) Processor 3200+ (1800.01-MHz 686-class CPU)
  Origin = "AuthenticAMD"  Id = 0x40ff2  Stepping = 2
  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=0x2001<SSE3,CX16>
  AMD Features=0xea500800<SYSCALL,NX,MMX+,FFXSR,RDTSCP,LM,3DNow+,3DNow>
  AMD Features2=0x19<LAHF,<b3>,CR8>

Bios DSDT seems to be reporting only 1800mhz and 800mhz (from PSS_ values)

This is all very confusing, why do powerd try to set other values than the ones given by bios?

Thanks,
Evren
