If you just need to suppress those during apple booting, making them

dhcp-option=net:#apple-boot,209,pxelinux.cfg/default
dhcp-option-force=net:#apple-boot,208,f1:00:74:7e

will do it:  "#apple-boot" means "not apple-boot"

If you can get packet-captures of the transactions using wireshark or 
tcpdump, that would be very useful. The simplest method is

tcpdump -i <interface> -s 0 -w <file> on the machine running dnsmasq. 
Send the resulting file to me off-list. Dumps from the working and 
non-working configurations would be useful.
