I guess turning off the RAID converts the chips into standard SATA
controllers. I'll have to look into that. An nForce 4 machine recently
appeared at work, so I'll see what I can get it to do.

It looks like sos added support for atapci1 and 2 in this listing in the
ATAmkIII patchset.  While that patchset is in -CURRENT you'll have to
apply the -stable patches yourself. Search the list archives for the
location, soren posts it now and again.
