Is there a way to make it persistent so it survives reboots?
Also, compared to what I have on my phone, scaling_max_freq is currently reporting 600,000 although it's overclocked to 900Mhz (cpuinfo_max_freq)

EDIT: this post is obsolete. go to http://wiki.maemo.org/Kernel_Power
I have uploaded a new untested version of the community kernel that is supposed to support 250,500,550,600,700,750,800,850,900,1000MHz and sets the default max to 600MHz.
for freq >= 850 the DSP is set to 500MHz.
You should be able to change the frequency range as root using
The settings can be permanently stored in /etc/pmconfig
I currently don't have my USB cable (for reflashing) with me so I can't test it myself
If there are any volunteers please let me know whether it works.
Installing this new kernel is at your own risk, of course.
Be prepared to reflash the stock kernel per USB!
You can download version 19 from
LINK REMOVED
install all packages and the kernel-flasher-maemo last.
Good luck!
PS: this new version also includes the Joikuspot module

Is it sufficient to just:
dpkg -i kernel-m*
dpkg -i kernel-flasher-maemo_2.6.28-maemo19_armel.deb
init 6
...? cause I'm still getting:
# uname -r
2.6.28.10maemo-omap1
dpkg -i kernel-m*
dpkg -i kernel-flasher-maemo_2.6.28-maemo19_armel.deb
init 6
...? cause I'm still getting:
# uname -r
2.6.28.10maemo-omap1

yes, that should do it. 2.6.28.10maemo-omap1 is the kernel version, not the package version.
more elaborated commands:
please let me know if overclocking works and whether the limit is by default
600MHz. I can't test it myself till tomorrow
more elaborated commands:
Code:
wget http://maemory.com/N900/overclock/kernel-maemo_2.6.28-maemo19_armel.deb wget http://maemory.com/N900/overclock/kernel-modules-maemo_2.6.28-maemo19_armel.deb wget http://maemory.com/N900/overclock/kernel-flasher-maemo_2.6.28-maemo19_armel.deb dpkg -i kernel-m* dpkg -i kernel-flasher-maemo_2.6.28-maemo19_armel.deb reboot
600MHz. I can't test it myself till tomorrow

I got around to testing it, and unless Powertop is freaking out, the results are not expected.
I have set max scaling to 800000, and as you can see in the screenshot below, the CPU is spending time in the higher P-states (above 800mhz)
EDIT: I fired up Conky, and it shows an idle (min.) speed of 500 Mhz and 800Mhz under load. The min. scaling show be MUCH less.

I've just uploaded cpufrequtils to extras-devel. could you please show me the output of cpufreq-info ? thanks a lot!

Code:
cpufrequtils 006: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: omap
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 0.00 ms.
hardware limits: 250 MHz - 1000 MHz
available frequency steps: 1000 MHz, 900 MHz, 850 MHz, 800 MHz, 750 MHz, 700 MHz, 600 MHz, 550 MHz, 500 MHz, 250 MHz
available cpufreq governors: ondemand, userspace
current policy: frequency should be within 250 MHz and 800 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).
cpufreq stats: 1000 MHz:0.00%, 900 MHz:0.00%, 850 MHz:0.00%, 800 MHz:13.93%, 750 MHz:0.19%, 700 MHz:0.47%, 600 MHz:16.40%, 550 MHz:0.51%, 500 MHz:68.50%, 250 MHz:0.00% (623)
Installing your cpufreq-utils package does not automatically enable the cpufreq daemon, does it?
