I do remember that with PIIX, one of the BSDs failed, while all the others
worked just fine. I don't remember which one. Could have been OpenBSD. Skimming
through the source, it looked as if it was searching for an IDE controller and
only then activated AHCI on it - which totally contradicts the usual workflow
of AHCI on ICH.
