No dice.  I grabbed the latest if_bce.c from cvs HEAD, made the tweaks
(provided by Jason) and rebuilt the kernel.

I was able to trigger the watchdog timeout in less than 5 minutes.  I did
not get a kernel panic, and kernel was built with INVARIANTS and
INVARIANT_SUPPORT.

Any other tests/experiments it would be worthwhile for me to run?
