The SATA controller device ID is different according to

the onchip SATA type set in the system BIOS:
Device                              Device ID
SATA in IDE mode             0x4390
SATA in AHCI mode           0x4391
SATA in non-raid5 driver     0x4392
SATA in raid5 driver           0x4393

Although the device ID is different, they use the same AHCI driver
.The attached file is the patch for adding these device
IDs for ATI SB700.
