hi there,
the following addition makes ahci work on my MCP77.
if this piece is present together with the ide
compatibility patch, and the disk is not in ahci
mode, ahci must be disabled in ukc to force the
chipset into compatibility mode.
i experimented with both modes because the other
systems on the disk can't do ahci yet.
just out of curiosity, is there a reason why not all
PCI_PRODUCT_NVIDIA_MCP*_AHCI_* id's are listed?
