In other words, if you have = "device ahci" (or "device siis" or "device mvs") will you will always = get adaX devices, whether or not you have "options ATA_CAM" in your = kernel config file? Does "options ATA_CAM" work with "device ata" or the modular ATA = subsystem? Is that the intended use of "options ATA_CAM": to provide = adaX devices and a CAM interface for accessing ATA devices?
