That is correct. If there is no cable the kernel cannot initialise the interface and so creates no routes on it. Al you are left with then is the ppp route.

I have noticed that when I boot the machine without the ethernet cable attached kppp works as expected and I can access the internet via my modem without problems. It is only once my machine has experienced a much faster route to the internet via my ethernet port that it refuses to send packets through the much slower modem. I think you may have therefore hit the nail right on the head by suggesting I look at modifying the costs of the two routes.
