Apparently this chip also supports SAS disks, will these work with the

ahci is definitely SATA-only, so I wonder how they modified AHCI to support SAS transport...

Jeff while are on that subject a further reminder - AHCI is also breaking
Marvell PATA device support for this reason and we now have months of
regressions because of that.

Refresh my memory...  what is the problem with loading pata_marvell first?

AFAICS, if you load pata_marvell before ahci, it will grab the PATA disks and the PCI device itself.
