mknbi knows the size of each of the segments and how much space they are
allowed to have, it doesn't blindly copy everything. The only
possibility for overlap is if the kernel is > 576kB which may not have
been checked in the past, but in that case it won't load at all even in
5.0. mknbi also assumes that Etherboot is not using the first 576kB. If
Etherboot is run from 0x20000, then a zImage kernel would obviously
overwrite it. A bzImage kernel should be ok.

This is the Perl mknbi I'm talking about. I take no responsibility for
the old mknbi from netboot.
