Interesting idea... but how do I know if udev gets an event?

I can tell you that out of all the logs (*) in /var/log/ that only these
three get the "r8169: eth0: link down" message:
   kern.log
   messages
   syslog

*: Specifically:
  cd /var/log
  tail -f * */*
 (and wait for it to settle down, then pull out the network cable)
