If that's the case, I'd rather the CK804 and MCP04 SATA device IDs be added to sata_nv, since we want distributions to support these SATA controllers when silicon does become available. > > > Removing IDs from amd74xx.c is a bad idea, > > > it breaks boot on systems already using these IDs. > > > > I assume these systems will be able to boot using the libata > > subsystem.

I kinda chalk this up as an inevitable kernel upgrade issue (they'll be getting support for NVIDIA SATA under libata with eventual device hotplug support, at the cost of some system reconfiguration).
