Looks OK, although I'd check that the "filename" line works from a
standalone tftp client. This is what I have...

dhcpd.conf (simplified):
subnet 10.1.1.0 netmask 255.255.255.0 {
    range		10.1.1.200 10.1.1.201;
    next-server		10.1.1.10;
    filename		"/tftpboot/pxelinux.0";
}

[sysadmin at 10.1.1.10]$ ls -lR /tftpboot
/tftpboot:
lrwxrwxrwx    1 sysadmin   21 Jun  3 15:38 memdisk -> syslinux/memdisk.2.09

[sysadmin at 10.1.1.10 tftpboot]$ cat /etc/xinetd.d/tftp
service tftp
{
	socket_type             = dgram
	protocol                = udp

	server_args             = -s /tftpboot

}
