	This RAID thing is an illusion caused by atapicam misreporting the
channel - my SATA drive is *not* connected to a RAID controller it is
connected to the VIA 6420 SATA controller - which is also not an AHCI
controller (at least it does not report as AHCI). The misreporting becomes
clear when I have atapi-cd loaded as well viz:

acd0: DVDR <TSSTcorp CDDVDW SH-S223F/SB00> at ata6-master SATA150
acd1: DVDROM <LITE-ON DVD SOHD-167T/9S19> at ata1-master UDMA33
. ..
