I don't get it. Why is it rejected then ? If I'd like to use the ahci mode of the ich7 r/m driver I just compile it into the kernel, else the piix ?!
Well, it's probably okay if you know what you want but when ich's are present, most distributions choose to load both ahci and ata_piix while usually preferring ahci. That should generally work. If BIOS didn't set it up properly, ahci will fail to load then ata_piix is loaded instead. The thing is that BIOSen are weird and it's quite possible that switching to ahci mode might have other side effects. For one, ACPI methods could have been written assuming certain mode and suspend/resume might choke if the controller is put into different mode from what BIOS has configured.
