BIOS configuration for a Gigabyte GA-X58A-UD3R and i7 Intel processor

I am putting together a DIY system using a Gigabyte motherboard
and the Intel i7.  I plan on running FreeBSD 9.0 as the based OS.
I have a Seagate 1 TB Barracuda for the hard drive connected to
one of the sata controllers.

I've got a couple of questions regarding the SATA setup.

The motherboard has an Intel ICH10R South Bridge controlling
6 SATA2 (3.0 Gbs/s) devices, Gigabyte controlling 2 GSATA2 devices
(3.0 Gb/s) and a Marvell 9128 SATA3 (6.0 Gb/s) devices.

I currently have the HDD connected to the ICH10R.  My first question
is simply confirmation of what my googling seems to have turned up -
that this controller is supported by FreeBSD.

2nd question, the BIOS setup lists this controller mode as "IDE"
and the other possible values are -

  "IDE" = Disables RAID for this SATA controller, configures the
          controller in IDE mode

  "RAID" = Enables RAID for this SATA controller

  "AHCI" = Configures the SATA controller to Advanced Host Controller
           Interface mode to support enabled advanced Serial ATA
           commands such as Native Command Queuing and Hot plug.

Which mode is the best for FreeBSD?  The BIOS default is IDE.  I am
currently only using 1 HDD so I am not currently interested in RAID.
Is AHCI supported?

NOTE: these modes are listed for all three SATA controllers.
