I think you're right as the pata driver omits the cd detect just
before the ata_piix failing.

I've cut the kernels down, removing usb and a bunch of stuff, ensuring
settings are identical. Here's a diff between from
xen(fails)->native(works). As you can see there really aren't that
many differences.. maybe you can spot something significant?
