For yet unknown reason, MCP89 on MBP 7,1 doesn't work w/ ahci under linux but the controller doesn't require explicit mode setting and works fine with ata_generic. Make ahci ignore the controller on MBP 7,1 and let ata_generic take it for now. Reported in bko#15923. https://bugzilla.kernel.org/show_bug.cgi?id=15923 NVIDIA is investigating why ahci mode doesn't work.
