Smile Frequency scaling showing wrong frequencies Intrepid C2D


I am having trouble with frequency scaling in ubuntu 8.10. It is only showing 2 available frequencies as 600mhz and 700mhz. I searched the web and found nothing that seems to help my case. So I write to my fellow linuxquestion friends and hope they have an answer. I will provide a few things but let me know what else you need.

$lsmod | grep cpu
Code:
acpi_cpufreq           15500  0 
cpufreq_ondemand       14988  2 
cpufreq_powersave       9856  0 
cpufreq_conservative    14600  0 
cpufreq_stats          13188  0 
freq_table             12672  3 acpi_cpufreq,cpufreq_ondemand,cpufreq_stats
cpufreq_userspace      11396  0 
processor              42156  2 acpi_cpufreq,thermal
$sudo cpufreq-info
Code:
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 0
  hardware limits: 600 MHz - 700 MHz
  available frequency steps: 700 MHz, 600 MHz
  available cpufreq governors: ondemand, powersave, conservative, userspace, performance
  current policy: frequency should be within 600 MHz and 700 MHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 600 MHz (asserted by call to hardware).
analyzing CPU 1:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 1
  hardware limits: 600 MHz - 700 MHz
  available frequency steps: 700 MHz, 600 MHz
  available cpufreq governors: ondemand, powersave, conservative, userspace, performance
  current policy: frequency should be within 600 MHz and 700 MHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 600 MHz (asserted by call to hardware).
a section of dmesg that I thought might be of need
Code:
[   19.011883] ACPI: WMI: Mapper loaded
[   19.732834] warning: `avahi-daemon' uses 32-bit capabilities (legacy support in use)

I will provide anything else necessary. Scaling seems to work fine between the two detected frequencies. I almost forgot to add this:

I thought I would share with anybody looking at this thread cpufreq-info says 1.6GHz and 1.87GHz. I am going to look into see if Intel has any info on this. I reset the BIOS to default settings. I must have had a setting that caused the kernel to see a small frequency. Anyway hope this helps other people.
