There's a package in -devel that somehow enables sudo to work (I'm not sure if it's cause I changed the password for user, or the pass for root).
If you want to try to see which application it is be my guest.
Edit: it's one of these http://pastebin.com/1mA5JbHF
But no one knows it.. hum .. right...

Hey all..
I think i discover the problem.
Somehow, before reflash, my \sys\* is on read\write\execute to my user.
But actualy, i cant modify it (i can, but before restart, everything goes back to read only).
Any one knows how to change it ?
I've googled a little but..nothing..

I'm trying to change the value on, for exemple:
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
with this command:
sudo echo 1000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
using: queen beecon widget
Please dont tell me it doesent work..i've donne it before re-flash my device as you can easly see by editing my queen_beecon file on:
http://www.4shared.com/dir/37234484/...on_Widget.html
If that permissions are set by kernel-modules..maybe..before i was using maemo 23 i thing with OC ..now i'm using maemo25 (are that modules included on that you're talking?)
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

sudo echo 1000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

/sys is a virtual file system where you cannot store files. it is just for the communication with the kernel.
changing permissions on /sys is pointless. there were no changes on /sys in the different kernels version.
I have removed the remaining occurrences of "sudo" before commands in my tutorials - it was a mistake. sudo works only with specific commands but not with echo etc.
If you really want to use "sudo" with scripts, create a script which will run as root (i.e. no sudo in the script) and put an entry in /etc/suders.d so that can run the script using
"sudo script"

Actualy, what i need is to use Queen Beecon Widget with some CMDs like: echo 900000 > /sys/devices/.../scaling_max_freq.
So, what it's needed to do ?
Add the executable of Queen Beecon Widget t Sudoers file?
It's that? If is...what to put in suddoers, please.
Actualy, to use the "scripts" i've created on Queen Beecon Widget, i need to change permissions on that files /sys/devices/.../scaling_max_frq , and thats boring because when i reboot the phone, i need to set them again and again.
Queen Beecon Widget dont allow you to put CMDs with root or sudo gaind root.
* I still dont undurstanding why i can do it before re-flash, but, if i go throught the problem..dont worrie *
Thank you all for helping.

Try "echo 1000000 | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq"
You may need to add "tee" to the sudoers configuration first.

just used:
echo "echo 900000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" | sudo gainroot
it works...so, finaly, i've back my own Overclock UI..like i had before reflash my n900. Still strange why it works before and this time it takes 4 times (x) more commands, but..just fine..it works...hardly, but..it works... thank you for all of you that help me sugesting me to try some commands and explaining me some things.
Sorry to QWERTY12, maybe not a rootsh problem ( :
Cheers to all.
