As far as why the offset wasn't present, sorry about that.  I guess
our tool chain is a bit more different than upstream, I've had a bit
of trouble generating kdump files for upstream.

Your manual calculations look correct to me though and it should work.
 If you can send me the vmlinux/vmcore triplet (I don't think I need
the kallsyms) then I will look at this today.  Can you post it
somewhere I can download it?

Sorry for the delay I was on vacation.

thanks,
Andy
