May I assume you have control over the "filename" in DHCP config? In
that case, you could use something like
	tftp://10.0.0.1//kernel.nbi
as filename, which should be parsed by etherboot to be a "hidden"
next-server statement.

If you do not even have control over the filename that goes through the
wire: Do they send one at all? If not, the DEFAULT_FILENAME (option name
may be a bit different - don't remember) might be your friend.
