[coreboot] suport for AMD 770 (RX781) ? SATA III ?

I know I said I'd pick one of the GSoC motherboards, but after that coreboot got DDR3 support,
and since I want to have a computer for a long time, and it may help compiling quicker,
and so... I'd like to go for AM3 for the DDR3 support (I'm thinking Phenom II X4 910e or 905e) .

I've seen this motherboard but I'm not sure the chipset is supported in coreboot.

(it has a serial port and, from the picture, socketed BIOS ROM)

It lists
AMD 770/SB710

I think AMD 770 is an alias for RX781, and I think this is an RS780 without IGP .
Is it included in the RS780 support contributed by AMD ?

It's not listed in
Maybe because it's not yet tested ?

I imagine it is implemented (maybe not tested on bare metal)
because I saw this message:

But I'd like confirmation of the status before buying the board just in case
I'm doing something really silly.

Another question is about the U3S6 sold with this card.
It's a PCIe 2.0 (x1 ?)  card with 2 USB3 ports and 2 SATA III (6Gb )
ports. I think it has a Marvell 88SE9123 SATA III controller.
I don't find it in the supported chipset list. Yet it appears to have some
linux driver (I still haven't foudn if there is some blob issue, Mavell
calls it "open source linux driver"). Does it mean coreboot
(payloads?) can't boot an OS from a disk connected to it,so I should
have a disk connected to the 3Gb SATA in the motherboard ?

I can buy the same card without the SATA III (6Gb) add on card,
and I could at any time buy another add on card, so I'll probably do that
if I can't use SATA III with coreboot anyway.

I'll buy two 4Gb 1333MHz DDR3 SODIMMs if I can find them,
and leave two more sockets for the future ,and a second hand
Nvidia PCIe x16 fanless card for graphics.

Sorry not to be able to send the required information since I still don't
have these components and can't run diagnostics tools. I'm just asking
if at first sight there's somethign weird with this.

Thank you.
