I did this, and it had no effect. To be specific, I moved the ethernet
cable from the eth0 port to eth1. Then I edited dhcpd.conf to respond
to the MAC address of eth1.
Then, instead of using /tftpboot/pxelinux.cfg/default, I created a
custom file for the specific MAC address. I loaded it with APPEND
options to specify all the network parameters explicitly. It loaded,
but it didn't seem to change anything.
I am worried because dhclient (after the kernel boots) is listening to
the infiniband and loopback devices. This just seems wrong. Is there
anything I can do about it?

OK. This is a project for next week.

From the beginning iptables was set to accept anything from the private
network where the clients live, and also for the whole range of IP
addresses on that net. Here's part of the output of iptables -L -v:
pkts bytes target prot opt in out source destination
0 0 ACCEPT all -- eth1 eth1 anywhere anywhere
75581 2526K ACCEPT udp -- any any 192.168.0.0/24 anywhere udp
1238 162K ACCEPT tcp -- any any 192.168.0.0/24 anywhere tcp
