Sorry, I should have broken the paragraph there, it was more of a
assertion that IA64 is fine, i.e. no reason to change.
Ok. Actually, the patch doesn't change the behaviour on IA64, it just
refactores it because of the x86_64 change.

To address all of Dave's concerns with the submitted patch. It was
simply a question of, if there is a simple workaround can we just use
that instead to minimize the changes. I didn't mean to imply that
accessing the arch specific dump header was bad idea, it's just that
its arch specific and requires a rather large patch.
I'll take a look if I can fix the problem with a workaround. Give me a
few days to find time ... ;-)
Thanks,
