Then there is a correction required to /sys/dev/ata/ata_chipset.c - mine
identifies itself as:
atapci0 at pci0:0:31:2: class=0x010180 card=0xff101179 chip=0x27c48086
rev=0x02 hdr=0x00
vendor = 'Intel Corporation'
device = '82801GBM/GHM (ICH7-M Family) Serial ATA Storage
Controller'
class = mass storage
subclass = ATA
.. where 0x27c4 is "legacy" mode and 0x27c5 is AHCI mode,
