    This is on an IBM Thinkpad T23:

    cpufreq: Intel(R) SpeedStep(TM) support $Revision: 1.7.2.2 $
    cpufreq: chipset 0x3 - processor 0x2
    cpufreq: read at pmbase 0x1000 + 0x50 returned 0x0
    cpufreq: read at pmbase 0x1000 + 0x50 returned 0x0
    cpufreq: writing 0x1 to pmbase 0x1000 + 0x50
    cpufreq: read at pmbase 0x1000 + 0x50 returned 0x1
    cpufreq: change to 0 MHz succeded
    cpufreq: read at pmbase 0x1000 + 0x50 returned 0x1
    cpufreq: read at pmbase 0x1000 + 0x50 returned 0x1
    cpufreq: writing 0x0 to pmbase 0x1000 + 0x50
    cpufreq: read at pmbase 0x1000 + 0x50 returned 0x0
    cpufreq: change to 598 MHz succeded
    cpufreq: read at pmbase 0x1000 + 0x50 returned 0x0
    cpufreq: currently at high speed setting - 598 MHz
    CPU clock: 598.500 MHz (731.500-598.500 MHz)

    The low speed setting looks ok, but the high one is obviously wrong.
    It's a 1.13Ghz CPU, /proc/cpuinfo lists it as this:

    vendor_id : GenuineIntel
    cpu family : 6
    model : 11
    model name : Intel(R) Pentium(R) III Mobile CPU 1133MHz
    stepping : 1
    cpu MHz : 1132.406
    cache size : 512 KB

    The chipset in this machine is an Intel i830 chipset. Let me know if
    there's anything else useful I could do to provide further info.
