Chainloading Xen iPXE with dnsmasq

I know how to do this with ISC DHCPD but I am stuck in an environment with dnsmasq. So far I can deal with the case where it is not iPXE with:

dhcp-match=IPXEBOOT,175
dhcp-option=175,8:1:1
dhcp-boot=net:#IPXEBOOT,undionly.kpxe
dhcp-boot=net:IPXEBOOT,http://<boot server>/boot.php

but I would like to dhcp-match to IPXEBOOT only when iscsi, menu, ... features are available.

Has anyone else managed to solve this?

One option would be to have your DHCP infrastructure set up to hand out only undionly.kpxe, and have an embedded script within undionly.kpxe which boots from http://<boot server>/boot.php.
