AMD/ATI SB700 support to Ubuntu

[Shane Huang]

Greetings:

More SATA device IDs should be added to support sb700 completely,
otherwise
Ubuntu may fail to be installed on ATI SB700 when set "onchip SATA type"
in BIOS into "AHCI" mode. There are four SATA related device IDs in
SB700:
0x4390, SATA in IDE mode
0x4391, SATA in AHCI mode
0x4392, SATA in RAID mode with Promise non-Raid5 driver
0x4393, SATA in RAID mode with Promise Raid5 driver
This is different from SB600, there is only one SATA Device ID in SB600,
which is 0x4380.

In the previous SATA patch to SB700, we only add 0x4390. This patch
provide the other three device IDs, otherwise Linux might NOT be
installed
when set SATA into "AHCI" mode in BIOS.

Could you please add this patch into Ubuntu 7.10 before it's release?
Because I'm afraid that the kernel in Ubuntu 7.10 may not support this
patch. We have submit this patch to kernel.org, and we can provide the
the upstream commit if you want when it's accepted.
