More important probably would be `pciconf -lvcb`.
Intel controllers after ICH6 change both ID and set of resources,
depending on AHCI enabled in BIOS. There is separate set of IDs for
controllers with AHCI enabled. As I can see, Linux handles ID 0x27c4 as
non-AHCI SATA. If for some reason this ID could be used for both modes
(I have doubts), we may try to set AHCI_Q_NOFORCE flag to make driver
check PCI class/subclass, if it is correct there.
