So, does that mean if you omit "options ATA_CAM" and have "device ahci" =
you will get adX devices, not adaX devices?  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?
