I think the Marvell SATA chipset work is still a work-in-progress. It
may still be supported by the ata(4) driver, but that driver typically
does not support any SATA-specific features, such as NCQ.

We use a handful of the SYBA SY-PEX40008 cards
manage a handful of drives with ZFS. The cards have some RAID features,
but you can simply plug disks in and use them without involving the RAID
layer. If your motherboard supports it, you can even disable the Option
ROM from showing up on boot.
Overall, the performance has been pretty good. The siis(4) driver has
full support for the Sil3124 chipset that these use and supports all of
the bells & whistles like NCQ and FIS-based switching for port
multipliers. They have also been very stable. The only gripe for me is
that it's only 1x PCI-E, instead of 4x, so you won't get full
performance out of it once you have 4 fast drives attached.
