It should work yes, even for a bug in networking stack.
Yes, you should take the source address you're supposed to have once
machine running. I suspect it could work with another IP address, but
using the normal one makes sure you dont hit some anti spoofing rule in
your LAN.
To check if netconsole works (after boot), you can try
dmesg -n 8
modprobe pktgen
You should see on remote machine :
pktgen: Packet Generator for packet performance testing. Version: 2.74
