There's no workaround at the moment. The root cause is the BIOS seems to
be broken and incorrectly disables the PCI device for the PATA
controller when the SATA controller is set to AHCI mode.
A PCI quirk might be doable to forcibly re-enable the PATA controller so
that ata_piix can drive it, depending on what exactly the BIOS has done
to switch it off..
