Thanks, this worked.  (e1000_poll_on being a function in the driver).

Except...

Now it seems to freeze up after about ~60 (usually 62) packets on the
input.  This seems to be an input freeze rather than a queue full
freeze, as packets are going in/out of the queue.

(reverse Roman's changs, reinstall and reboot and the input is no
longer feezing up, but then the output doesn't work... ).

Now for what I'm going to do TODAY I'm OK, as I'm using different
ports for inputs and outputs (its load balancing for an IDS), but I'd
like to figure out what/how to get this working in general.
