Ps: I imagine how many people are running their servers or desktop computers using the legacy PIIX driver, just because the BIOS setting is wrong (IDE instead of AHCI). In my case I just ignored the "RAID mode" option because I don't ever use RAID. Don't you think it would be nice to add a warning message when the kernel detects AHCI capable system like ICH10 and the kernel is misconfigured using the legacy PIIX driver? It could be something like that: "AHCI capable chipset: use ahci driver instead".
