[maemo-developers] Turn off all devices but processor (and networking module) on N800

[From: Sungwon Yang]

Hello,

I have a N800 and what I'm going to do is using N800 as an embedded
board for research purposes.
I need to evaluate processing time and power consumption when I run my
algorithm.
Is it possible to turn off all devices such as audio, camera,
display,etc which are not related to my work but still consume power
and may need processor's resource.
If possible, I'd like to disconnect those devices at very low level,
thus it looks like such devices do not exist.
I have no idea where I should start from.
Any help or hints would be really appreciated.
Thank you
