What I have noticed is when I enable Intel Raid support AHCI is on by default, maybe it used AHCI if drive is capable?! There are also performance regressions from within used bios. What mainboard are you using Erik? All mainboards with ICH6R I saw and had (925X,925XE) offer options to enable AHCI.
