This was fixed by upgrading to some version of 1.5Z (sources CVS'd about a
week ago).

I don't know if the messages & the failure were related or not.

After dropping in a 1.5Z kernel (which eliminated the errors), I suddenly
realized/remembered: GENERIC kernels have the GATEWAY option turned off.
I did a sysctl -w net.inet.ip.forwarding=1 on the live system, and things
work again.

I don't know if the 1.5Y kernel would have worked (despite the errors) if
I'd set forwarding=1.

Anyway.  Pilot error.  Mea culpa.  Nevermind.  Sorry.  (^&
