Well going on the pcidump output, if anything the ahci part should be MCP77_AHCI_6. To clarify, when you have the machine in AHCI mode it attaches as ahci but port resets prevent devices attached to the controller being found? If this is the case you should confirm that it works when AHCI_6 added the ahci.c not AHCI_1 as you had in the diff (which is now renamed anyway). The pciide part has been comitted with the name fix.
