 It's probably not; I was thinking more about ACPI when I asked.
 There's still no entry in pcidevs for that, so unless you have a bios
 option to turn it into ahcisata it's probably not going to do any
 If it's a viaide(4) that we just don't know about, you might be able
 to get it to work by adding it to the match logic, but the value of
 the product ID makes me think that isn't too likely.
