2.6.18-rc7-git1: AHCI not seeing devices on ICH8 mobo (DG965RY)

[Robin H. Johnson]

[Please CC me, I'm not subscribed.]

Recently picked up some new hardware (without sufficiently researching
it), and I have found that the AHCI driver does NOT see my SATA optical
device at all.

CPU: Core 2 Duo E6400
Motherboard: Intel DG965RY
DVD: Plextor PX-755SA, SATA DVD burner

I don't have any SATA hard drives on hand (I'm using a 3ware IDE controller for
storage presently), so I haven't tested with them yet, but I intend to pick
some up this afternoon.

On a separate issue, this board incidently is also the one mentioned in
previous LKML posts that has a presently unsupported Marvell IDE controller.
Jeff Garzik said he was asking Marvell for specs, does anybody know how that
went, or did anybody try to prod around with the controller?

Details as follows:
