you could also install lehtos ulv 250-800mhz kernel and adjust the speed to 900mhz giving you exactly what you want

when you install the kernel

open up xterm

type sudo gainroot

then type

vi /etc/pmconfig

press enter this will bring up the pc config where you adjust the cpu speed

scroll down to max where it says 600000

press i on the keyboard this will put you into editing mode delete the 600000 and simply put 9000000

when you have done this press esc on the screen of the n900 this will exit editing mode now to save the changes

make sure you have exited editing mode (press escape a couple of times to make sure) nw you need to enter the command

:w /etc/pmconfig

to do this press the white arrow on the n900 keypad and then press the ? mark key then press the w key and type the above and press enter this will save it

now enter the command

:q and press enter

then type reboot and press enter

when phone starts check conky to make sure you have adjusted the max to 900mhz if you have saved it right you will have adjusted it

please note this is apermanent change and this should be adjusted when you try other kernels , before installing other kernels allways set the max back to 600mhz
