[PATCH] SATA support for Intel ICH7 - 2.6.10 - repost

[Jason Gaston]

Reposting patch with word wrap turned off.  Please let me know if this is still not formated correctly.

This patch adds the Intel ICH7 DID's to the ata_piix.c SATA driver, ahci.c SATA AHCI driver and quirks.c for ICH7 SATA support.
If acceptable, please apply.

Thanks,

Jason Gaston
