Hi! This is most probably not an arch issue, but I dare to ask for what you think.
I'm using laptop-mode-tools with cpufreq on my Msi Wind netbook to limit CPU frequency when on battery. LCD brightness control works fine and HDD APM also. But when it comes to CPU - conky shows that it's still running with its maximal 1.6GHz (well, actually it shows various values between 1575 and 1602 MHz) while gnome panel applet shows 800MHz.
So my question is - which of them should I believe? Or maybe some other way to check that?

cpufreq-info
It'll show you the real value...
My victim you are meant to be
No, you cannot hide nor flee
You know what I'm looking for
Pleasure your torture, I will endure...

Thank's. Now I don't know why conky tries to cheat me, but it's not that important...

Are you using freq or freq_dyn in your conky config? If you are using freq, it is just taking the same value displayed in /proc/cpuinfo, which is what the Gnome applet is showing. If you are using freq_dyn, it is making some calculations and figuring out the frequency on its own, which is much more accurate.
Speedstep isn't really changing the real clock speed, it does some other kind of voodoo.
I've actually found that on my Asus EeePC 901 (also Atom powered), underclocking with the FSB gives much better battery life than Speedstep, I get about an hour more by disabling Speedstep and underclocking to 1.25Ghz.
