Subject: cpufreq and kernel >2.6.15.6 is limited

It seems that any kernel on my Dell Inspiron 5100 after 2.6.15.6
(including 2.6.17-rc5) 'breaks' my cpufreq in that up to and including
2.6.15.6 I can scale between 300MHz-2.4GHz, but after (starting with
2.6.16) I can only scale between 2.1GHz and 2.4GHz.
I've attached the files, sorted by kernel, I assume may be helpful. Let
me know if you need any more.

driver: p4-clockmod
CPUs which need to switch frequency at the same time: 0
hardware limits: 300 MHz - 2.40 GHz
available frequency steps: 300 MHz, 600 MHz, 900 MHz, 1.20 GHz, 1.50 GHz, 1.80 GHz, 2.10 GHz, 2.40 GHz
available cpufreq governors: conservative, ondemand, powersave, userspace, performance
current policy: frequency should be within 900 MHz and 2.40 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 900 MHz.
