Very confusing: a PC with an intel PRO/1000 network card was booting via PXE using the heavy duty boot environment but it was very, very slow. Running tcpdump I saw errors trying to reach port 0 for tftp. The most recent possibly related change was the dhcp setup for the APC AP7920 switched rack PDUs. Some searching in the manual found that the APC devices use a specific client vendor identifier so I can use that in the dhcp configuration. I updated the post to reflect this new knowledge: only send the APC vendor cookie to APC devices requesting it.
