ixp4xx support in newer kernels

Hi Huys,

I am starting off on a new project with ixp4xx based chip.
I already have it working in 2.6.19 kernel.
How well are ixp432/ixp435 chips supported in new kernels.
I would like to move it to 2.6.35 kernel.

If I want to look at the latest patched for IXP4xx, is there good spot
to look at ( gitweb or URL).

Thanks
