There is a native kernel on the demo CD as well as the xen/linux one.
They have very similar configs, so it's often interesting to compare the
behaviour of them.

As you point out, things go wrong too early to be influenced by anything
in xen/linux. However, trying booting different versions of native linux
is useful as it will tell us when the issue was fixed in linux and hence
identify what we need to do.
