ICH9 Controller on Asus P5K-E showing up as "Intel AHCI controller"

Thank you both! I figured it was operating normally (I've noticed no
performance problems or oddities from the controller or devices
attached to it). I guess in trying to find out what was going on, I
saw this comment:

    /* is this PCI device flagged as an AHCI compliant chip ? */
    if (pci_read_config(dev, PCIR_PROGIF, 1) != PCIP_STORAGE_SATA_AHCI_1_0)

Which if I read the comment literally makes me believe if that does
not return non-zero/NULL, that my controller is not AHCI compliant.

But if it's falling back on a perfectly working generic AHCI
implementation, what it reports at boot time is moot. :)

Thanks again guys!
