Suggested starting kernel for new PPC405GPr board

So I've got my boot loader (u-boot) in seemingly good shape on my new target board, it's time for me to start thinking of getting an actual Linux kernel working here. This is bound to be a FAQ, but are there suggestions for a starting point? For example, is the kernel at www.kernel.org likely to be useable?
