FWIW, Mike, I get the same thing on the quad xeon acer box as well. Been
meaning to report that for a while, as I have some extra debugging printf's:
>From dmesg:
acpi_cpu0: <CPU> on acpi0
acpi_cpu: CLK_VAL field overflows P_CNT register
XXX: cpu_duty_offset 0, cpu_duty_width 0, duty_end -1
acpi_cpu: CLK_VAL field overlaps THT_EN bit
acpi_cpu1: <CPU> on acpi0
acpi_cpu2: <CPU> on acpi0
acpi_cpu3: <CPU> on acpi0

}

}
Processor(\_PR_.CPU2, 3, 0x410, 0x6) {
}
Processor(\_PR_.CPU3, 4, 0x410, 0x6) {
