There exist buggy PXE clients which only work if the tftp server is at
the same address as the DHCP server. From your packet dumps, it looks
like that's true when you use dhcp3, and not true when you use dnsmasq.
I'd bet that's your problem. Run dhcp server and tftp server on the same
box, and it will work.
