There are 2 patches from the orion branch that is not available on the mainline kernel. They are:

I pulled the patches from the orion branch and created patch files that will work on the mainline kernel 2.6.30-rc3.
Download both and put them in the root directory of the mainline kernel. Then type:
patch -p1 < 0001--ARM-Kirkwood-CPU-idle-driver.patch patch -p1 < 0002--ARM-Kirkwood-peripherals-clock-gating-for-power-m.patch
Then build and install the kernel.
