[PATCH 2.6.15 5/6] ata_piix: IDE mode SATA patch for Intel ICH8

[PATCH 2.6.15 5/6] ata_piix: IDE mode SATA patch for Intel ICH8

[Jason Gaston]

Hello,

This patch adds the Intel ICH8 DID's to the ata_piix.c and quirks.c file for IDE mode SATA support.  This patch was built against the 2.6.15 kernel.  
If acceptable, please apply. 

Thanks,

Jason Gaston
