1) Find a way to take off the keypad lights as this contributes a lot of the heat.

echo "1" > /sys/devices/platform/gpio-switch/slide/disable

(but it disables the KBD unlock too - sometime it is advantage, if you have a magnetic case).

Do you have lots of background apps? They can make you cpu stay in a higher scale

Now my N900 is fast as hell. :-)

But it stays on 500mhz when idle. Is this normal?

if your plugged into usb via pc then i believe so yes :-)

I would recommend NOT to overclock your DSP!

Please do not REBOOT - use switch OFF-ON.

It has nothing with overclocking, see bug 7017 - https://bugs.maemo.org/show_bug.cgi?id=7017

this may sound daft but has anyone else had problems recieving text messages when signal is choppy after using an overclocked kernal?
two nights ago i was in work, where signal is bad, textin the missus, i updated the kernal to a fiasco 800/125 and havent recieved a message off her since. they come through when im in signal but if out of signal she sends and they dont come through when i get signal again. it definately has something to do with my changes because it is from that exact point onwards that i get the problem. havent read of a single other complaint like this any ideas?

for me, the 125MHz kernel stays at 600MHz most of time while the 250MHz stays at 250MHz.

Can you show an output of

cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state

while kernel has 125MHz capability?

then you have the older 2.6.28-Maemo18 package installed, not
the latest version 2.6.28-Maemo19. only the latest version supports OC.
just upgrade your package.

IIRC it was about 86,6% in 600MHz and the rest in 125MHz despite mostly idling...
