Description of problem:
I would like to request an update of the speedstep driver for power
management on newer laptops. The current speedstep driver is dated
1/2/03 and has not changed between U2, U3 or U4 beta. I would like to
request an update for U4 final or even U5 kernel such that newer
Centrino-based latops like the IBM Thinkpad T40 and T42 would be
The FC2 2.6.x kernel speedstep driver works well on these laptops, but
we'd like RHEL 3's speedstep driver to also work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. modprobe speedstep
Actual Results: dmesg shows
cpufreq: Intel(R) SpeedStep(TM) for this chipset not (yet) available
Expected Results: # lsmod | grep speedstep
speedstep 4652 0 (unused)
Older laptops like the IBM Thinkpad T30 work just fine.

Thank you for adding me to the CC list. Is this feature being planned for the
U5 kernel or is the U5 kernel already frozen?
Kernel changes are still being made to U5, although I'm not sure whether the
U5 requirements are now frozen. Rob/Peter, could you please follow up here?
I am reassigning to dff; this is a laptop issue. But, in general, the info at
has a guide that should provide the needed info.
The bug status ASSIGN_TO_PM has been deprecated. In the future please use
ASSIGNED and either add the PM to the Cc list or re-assign report to them.
Feel free to close this bug since we dropped this RFE in favor of using RHEL 4.
Closing as WONTFIX based on last comment.
