 The LiveCD attempts to load both "piix" and "ata_piix" modules when an
 Intel IDE or SATA controller is detected. Previously, IDE ports were
 handled by the "piix" module, and SATA by "ata_piix". However, it looks
 like this ability is deliberately broken in linux-2.6.22. See
 http://lkml.org/lkml/2007/7/20/171 for the error message.

 If this is true, we will have to either document the need for the "pata"
 boot parameter in such setup, or drop piix completely and force (IMHO, a
 bit raw) libata on Intel hardware.

 I cannot test this personally because I have no computer with both IDE and
 SATA drives on Intel controller.
