It needs to have an sh extension right?

Here is a 24H snapshot of ideal kernel under moderate use. SSH was on 50% of the time and I was almost always remotely logged onto the console and working on scripts in nano. Performance definitely seems to be better than stock when connected via wifi but potentially marginally worse when connected via 3G

  echo 850000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
end script
with "start kernel-maemo" you can activate it without rebooting
Can this be added to the kernel-maemo package?

My suggestion is to add sleep 120 at the start of this script. If it troubles upstart, then call another script with & and have that script sleep for a few minutes before setting the frequency.
That way, if you set a wrong parameter (there might even be changes - a voltage level that works in winter will not work on a hot summer day), you don't get a reboot loop, but have a small time to open an xterm and kill the script before it causes a reboot.

Great work providing vdd1_opps_vsel \,,/ I'm currently testing stable voltages for each scaling step starting from 250mhz (set min/max scale to 250). Stressing with pi_css5-vfp5 and nbench + file copy operations from mmc to internal and reverse. Right now 250Mhz is proven stable at 18 vset. Lowest vset is between 10 and 18 because 10 caused reset :P
