Re: viaide SATA DVD support

[Paul Goyette <paul%whooppee.com@localhost>]

Well, I can't really help here, but I had similar issues with device 
recognition when trying to use ahcisata on my motherboard's Marvell
88SE614X.

The device would fail to respond to an IDENTIFY command, and thus it 
"defaults" to an ST506 hard drive with rather limited geometry.  :)

Siknce I had many other SATA ports available, I just gave up on the 
Marvell controller.
