I think it won't work. This controller is AHCI-like.

There is unfinished driver for this family of controllers:
http://butcher.heavennet.ru/patches/kernel/ata/marvell/freebsd-working_module.tgz

Some people reported that it works. But it has several problems:
1. PATA support isn't implemented.
2. Error handling is incorrect, i think.

Now I have two motherboards with different controllers from this family.
And I'm going to finish it when I will have some free time.
