Since the problem seems hard, why not try a strange solution :-)

Try with a kernel that have 3c509 complied in directely and not as a
module, that way dhclient will not be run, the client will get its ip
as kernel boot argument from etherboot instead. I have a kernel for
i486 with 3c509 complied in at:
http://sociologi.cjb.net/ltsp/vmlinuz_3c509 the config-filed used at
compilation is http://sociologi.cjb.net/ltsp/vmlinuz_3c509.cfg
(nfs-swap patch is enabled)

With this kernel, you don't need any boot time arguments in dhcpd.conf
This is all that is needed.

    host foo {
        hardware ethernet      [Macaddress];
        fixed-address          [IP to offer];
        filename              ["/path/to/kernel"];
    }

Good Luck!
