yes, except I'm not quite sure why you need the pseudo ethernet device in
this context?

The privileged domain console access might also need some tweaking.

I'll try to remember what else needed changing when I added dom0 support to
Linux 2.6 -- but getting the PCI stuff working is the most important.

And please always include the RCS Id reference if you're copying an
arch/i386 file to arch/xen, so we can track what updates need to be merged.
