That's what I'm expecting to have to do, but unfortunately know where
to look for the changes I need to make is difficult.

Well, I think I *have* matched up the two structures, but we're still
not seeing anything. Where can I put breakpoints in the kernel to try
to work out why we're not getting any boot messages?

At the risk of asking newbie questions, how would I go about doing
this?

Thanks again for all the help so far, it's much appreciated.
