The Chipset can operate in 3 Modes: IDE, AHCI and RAID. Depending on the 
mode it has different PCI-IDs.

It is said to support (driver-)raid, but I don't use it.

When set to AHCI-Mode, the pci-id is 0x3b22. I use AHCI and it is 
supported by ahci in FreeBSD.

if it is not supported, you simply can't use it.
