Description of problem:
Hardware: Dell Latitide D600
On my Dell Latitude D600 laptop, cpuspeed fails to start even
with the speedstep-centrino module in the DRIVER= line in
/etc/cpuspeed.conf. The cpufreq_userspace module needs to
be loaded as well for cpuspeed to function. As a work-around,
I modified /etc/init.d/cpuspeed to treat the DRIVER= line
from cpuspeed.conf as a list of modules, and modprobe each
accordingly. Another work-around is to modprobe cpufreq_userspace
first, then re-run /etc/init.d/cpuspeed manually.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Power on the machine, cpuspeed fails to start due because
cpufreq_userpsace isn't present.

Patch to /etc/init.d/cpuspeed
I've got the same problem right now.
From rpm -q --changelog kernel :
* Tue Jan 27 2004 Dave Jones <email@example.com>
- Update to 2.6.2-rc2-bk1
- Set default CPUFREQ governor to userspace instead of performance.
This eliminates the problem I had with cpuspeed starting. Given
that, I'd consider this closed.
