Well, I had already compiled all the netgraph stuff into the
kernel before I saw this. And it did get rid of the netgraph
complaints as part of the next few panics.

I took the easy way out here and just ran
ifconfig xl0 inet 10.0.0.1
After that, no more panics and the ADSL modem worked first time.
Now, the final question: I have to implement something similar
on a 4.1-R system several thousand km away. There's no question
of upgrading it from 4.1 and I can't afford to have it panic.
Is it reasonable to expect that PPPoE will work OK provided I
add the netgraph stuff to the kernel and ensure the NIC is UP
before running ppp?
FYI, I also tried a different box that runs 4.3-R and it did not
experience the panic that was seen on the 4.2-R system.
Thanks a lot for the help with this.
