Hi,

I just added the ICH9 IDs to the ata-files, compiled a new kernel and
moved the disk to my new box. Now I can boot from ICH9R using AHCI.

But before submitting a patch, I'd like to know what ID 2921 might be.
Description: Desktop Non-AHCI and Non-RAID Mode (Ports 0 and 1). WIll it
ever be used?
Raid Mode on ICH9 is the same ID as raid mode on ICH8 (2822)?
(from: http://www.intel.com/design/chipsets/specupdt/316973.htm)

What I did to get my Gigabyte GA-G33-DS3R running:
g33# diff ata-pci.h.orig  ata-pci.h
169a170,173
> #define ATA_I82801IB_S1         0x29208086
> #define ATA_I82801IB_AH6        0x29228086
> #define ATA_I82801IB_AH4        0x29238086
> #define ATA_I82801IB_S2         0x29268086
g33# diff ata-chipset.c.orig  ata-chipset.c
1712a1713,1716
>      { ATA_I82801IB_S1,  0, AHCI, 0x00, ATA_SA300, "ICH9" },
>      { ATA_I82801IB_S2,  0, AHCI, 0x00, ATA_SA300, "ICH9" },
>      { ATA_I82801IB_AH4, 0, AHCI, 0x00, ATA_SA300, "ICH9" },
>      { ATA_I82801IB_AH6, 0, AHCI, 0x00, ATA_SA300, "ICH9" },
