Kernel parameters in Angstrom

fatbrain
Hi
I have baked an angstrom mini2440 image. The default kernel has power save
mode , I would like to remove  the power save mode from the default kernel.
Where do I make the changes. I can independently compile the kernel but
would like to have a single point build. 

I also need to include libstdc++, libts,libpng  to my base-image,
console-image and mini2440 images. Again where do I make the changes. 


regards
