ACPI / cpufreq on Presario R3120

[Ken Hughes <khughes@pacific.edu>]

I've got a Presario with an AMD XP-M 3000+ CPU (a 32-bit K8).
I can't get the acpi or powernow-k8 modules to load on the
2.6.6 kernel;  loading acpi gives this message:

  > acpi_processor_perf-0301 [1219] acpi_cpufreq_cpu_init : Unsupported 
address space [127, 127]

and powernow-k8 (with and without Pavel's patches) gives this:

  > powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 
1.20.08b - March 20, 2004)
  > powernow-k8: Too many lo freq table entries
  > powernow-k8: BIOS error - no PSB

I dumped the DSDT but it doesn't seem to have much info on the CPU.

The applicable section in my .config file is:

#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
# CONFIG_CPU_FREQ_PROC_INTF is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
# CONFIG_CPU_FREQ_24_API is not set
CONFIG_CPU_FREQ_TABLE=m
 

#
# CPUFreq processor drivers
#
CONFIG_X86_ACPI_CPUFREQ=m
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
# CONFIG_X86_POWERNOW_K6 is not set
# CONFIG_X86_POWERNOW_K7 is not set
CONFIG_X86_POWERNOW_K8=m
# CONFIG_X86_GX_SUSPMOD is not set
# CONFIG_X86_SPEEDSTEP_CENTRINO is not set
# CONFIG_X86_SPEEDSTEP_ICH is not set
# CONFIG_X86_SPEEDSTEP_SMI is not set
# CONFIG_X86_P4_CLOCKMOD is not set
# CONFIG_X86_LONGRUN is not set
# CONFIG_X86_LONGHAUL is not set

Any suggestions where I should look?  I'm not sure if it's a
APCI or cpufreq issue  -- Ken
