No, it's a real event.

Exactly, that's why this event is important. Without it, udev would not
be able to create the character device.
What is the issue you are having with this?

Agreed... I have 2.6.7 system here running udev-028 and OpenVPN, which
uses /dev/net/tun to create tunnel interfaces, and it works just fine.

Why do I re-receive that when I re-run udevstart? AFAIK just re-running
udevstart doesn't produce any real hotplug events.

Yes, this is exactly the event due to which udev creates the
/dev/net/tun character device :) However, it also gets dispatched to
/etc/hotplug/net.agent for some reason.

It does so because of the "net" in the class path. No harm done.
