    Subjectcpuinfo shows wrong MHz value
    I'm running kernel and /proc/cpuinfo and powertop and vmware are 
    unable to detect the correct speed (1.6 GHz) of the processor:

    cat /proc/cpuinfo
    processor : 0
    vendor_id : GenuineIntel
    cpu family : 15
    model : 1
    model name : Intel(R) Pentium(R) 4 CPU 1.60GHz
    stepping : 2
    cpu MHz : 13000.000
    cache size : 256 KB
    fdiv_bug : no
    hlt_bug : no
    f00f_bug : no
    coma_bug : no
    fpu : yes
    fpu_exception : yes
    cpuid level : 2
    wp : yes
    flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
    cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pebs bts
    bogomips : 3197.21
    clflush size : 64
    power management:

    According to dmesg the kernel detects the CPU correctly during bootup:

    Enabling fast FPU save and restore... done.
    Enabling unmasked SIMD FPU exception support... done.
    Initializing CPU#0
    PID hash table entries: 4096 (order: 12, 16384 bytes)
    TSC: PIT calibration matches PMTIMER. 1 loops
    Detected 1598.609 MHz processor.

    IIRC this behavior started some kernels ago, I can't remember which kernel it
    was. Is it possible that the ACPI information is wrong?
