Hi!
In my vostro 1500, with a T7250..,. cpufreq-info shows..
....
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 800 MHz - 2.00 GHz
....
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 1
....
1) How I can set that both cores switch his freq. at the same time?
2) When I unplug the power, the cpu runs at 800 mhz (!) but I have configured that the minimal speed should be 1.2Ghz, and when I plug the power again, the CPU still works at 800Mhz. I have configured the daemon, and seems to be correct.... but does not work. They set "current policy: frequency should be within 800 MHz and 800 MHz." automatically (!) and does not re-set to ondemand, when plugged again.
3) cpufreq-info shows that I have 2 governors, performance and ondemand... but I have only one (ondemand) loaded as module..
"available cpufreq governors: ondemand, performance"
bash-4.0# lsmod | grep cpu
cpufreq_ondemand 7672 2
acpi_cpufreq 8624 0
freq_table 3716 2 cpufreq_ondemand,acpi_cpufreq
processor 35864 3 acpi_cpufreq
My cpufreq.conf
bash-4.0# cat /etc/conf.d/cpufreq
#configuration for cpufreq control# valid governors:
# ondemand, performance, powersave,
# conservative, userspace
enabled="true"
governor="ondemand"# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="1.2GHz"
max_freq="2GHz"

Thanks for you patience!

You could try to change
min_freq="1.2GHz"
max_freq="2GHz"
to
#min_freq="1.2GHz"
#max_freq="2GHz"
because
1. these values are wrong
2. they usually don't need to be set, see here

Army, thx for your answer.
I did that, then, I restarted the service and shows 800 to 800Mhz.
Then I wrote it again, restarted the service.. and shows 1.2 to 2ghz.
My kernel is 2.6.30-ARCH #1

Your 'performance' is compiled in to the kernel, therefore will not show on a lsmod (because its not a module). My custom kernel has ondemand compiled in as well...
Are you using laptop-mode?

Yes, I'm using laptop mode
I'm still having trouble with cpufreq

Still unsolved
2) When I unplug the power, the cpu runs at 800 mhz (!) but I have configured that the minimal speed should be 1.2Ghz, and when I plug the power again, the CPU still works at 800Mhz. I have configured the daemon, and seems to be correct.... but does not work. They set "current policy: frequency should be within 800 MHz and 800 MHz." automatically (!) and does not re-set to ondemand, when plugged again.
Solved, I jus had to enable /etc/laptop-mode/conf.d/cpufreq.conf (wiki does not says this)
3) cpufreq-info shows that I have 2 governors, performance and ondemand... but I have only one (ondemand) loaded as module..
"available cpufreq governors: ondemand, performance"
solved.
Thanks a lot for your answers.
And... I found a weird behavior with "auto-hibernate" (laptop mode tools)
If I have my computer with running on battery, when i boot up my laptop, it turns inmediatley to hibernation mode (Battery 100%; 40% to hibernate)
