Subject: RE: [PATCH 2.6.23-rc4][reRESEND] ahci: RAID mode SATA patch for Intel Tolapai

This device has both AHCI and RAID modes that use the ahci driver.  Only
the RAID mode DID's are being added as the PCI class code support will
cover the AHCI mode.  Looking at the Generic, PCI class code support
section, it uses "board_ahci".  I assumed that they should be the same
as the generic class code support is working on this platform.

Thanks,

Jason
