Very good point! Should I do a simple respin of this patch adding the commit summary, or just do it for future patches? Thanks!

Like e65cc194f7628ecaa02462f22f42fb09b50dcd49 this patch enables 64bit DMA for the AHCI SATA controller of a board that has the SB600 southbridge. In this case though we're enabling 64bit DMA for another MSI motherboard, the K9AGM2 or MS-7327. It is new enough that all of the BIOS releases since the initial release (1.0 from 2007-02-09) work correctly with 64bit DMA enabled.
