Yes, some references for you:

http://www.linuxvirtualserver.org/arp.html

Get http://www.linuxvirtualserver.org/hidden-2.3.41-1.diff and apply
it. I just patched the 2.4 kernel with it using --dry-run. There are some
offsets but you can try it. It seems the arp code was not changed
last years. If you see something in this page that works for 2.3 you
can use it for 2.4
