Running 9.0-STABLE on a Soekris Net6501-70

[Herbert J. Skuhra]

Hi!

I am running FreeBSD 9.0-STABLE on a Soekris Net6501-70 which has the
following CPU:

CPU: Genuine Intel(R) CPU        @ 1.60GHz (1600.04-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0x20661  Family = 6  Model = 26  Stepping = 1
  Features=0xbfe9fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Features2=0x40e3bd<SSE3,DTES64,MON,DS_CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE>
  AMD Features=0x20100000<NX,LM>
  AMD Features2=0x1<LAHF>
  TSC: P-state invariant, performance statistics

Running a GENERIC (i386) kernel the cpu by default runs at only 600Mhz:

% sysctl dev.cpu
dev.cpu.0.%driver: cpu
dev.cpu.0.%parent: legacy0
dev.cpu.0.freq: 600
dev.cpu.0.freq_levels: 1600/-1 1400/-1 1200/-1 1000/-1 800/-1 600/-1 400/-1 200/-1

I either have to run 'sysctl dev.cpu.0.freq=1600' or run 'powerd' to
make the cpu faster.

Probaby related:

Can this be fixed or should I just add the following lines to
/boot/loader.conf:

hint.p4tcc.0.disabled=1
hint.acpi.0.disabled=1
hint.est.0.disabled=1

Thanks.
