Last time I tested it it wasn't dealing well with setting up combination 
mode for devices with optical media, and I don't have much hardware 
lying around which still uses piix. But if I can find some time I'll dig

the same...

Macs will come up with ahci if you boot via EFI rather than the BIOS 
compatibility module.
