what does modprobe ide_cd do for you? Remember its going to show up
as /dev/hd(b)? (c)? when its loaded.

If modprobe throws an error for that, something is *really* wrong.

the lspci from the native dump shows a bunch of undetected hardware, the
lspci from Xen looks quite a bit better.

I see ide_generic, but no ide_cd ... Give it a whirl and please post
back with results.
