Yep, should be pretty easy.  A while back I built a Katmai kernel in
arch/ppc based on the Yucca support and the differences were pretty
trivial -- as I recall, the Katmai has compact flash support that the
Yucca doesn't have, and the Yucca has a simple little FPGA with a few
registers that controls power to the PCI slots.
