I haven't run pxeboot via dhcp relay, but since TFTP server is TCP/IP
based and an IP can be specified, not sure about a hostname but that
would most likely work as well. In any case I see no reason this
wouldn't work, or why you would need a tftp proxy, although you would
need to make sure the tftp port (68?) is allowed to pass through any
firewalls etc :)

Below is the minimum options I found I needed to install/rescue systems
via pxeboot from my laptop, this way I don't need to burn CDs/DVDs all
the time, and nearly everything supports pxeboot, or you can get a
simple boot floppy/cd so it works well for me(tm).

$ cat /etc/dhcp3/dhcpd.conf
option domain-name-servers 192.168.0.254;

default-lease-time 1800;
max-lease-time 3600;

authoritative;
allow bootp;
allow booting;

subnet 192.168.0.0 netmask 255.255.255.0 {
        range 192.168.0.10 192.168.0.49;
	range dynamic-bootp 192.168.0.50 192.168.0.99;
        option subnet-mask 255.255.255.0;
        option broadcast-address 192.168.0.255;
        option routers 192.168.0.254;
	next-server 192.168.0.254;
	use-host-decl-names on;
        filename "pxelinux.0";
}
