NIC identification with PXE?

We use PXE and Etherboot to install FreeBSD 4 systems.  Until recently
all of these systems used Intel EtherExpressPro1000 82540EM NICs so all
that was necessary was to have the DHCP server reply with the
"e1000.zpxe" file.

Now systems that use Broadcom Tigon 3 5721 NICs are being introduced
which require the "tg3.zpxe" file.

Is there a mechanism by which the DHCP server can automatically
determine the model of NIC that is being used so that it can reply with
the matching file?  We use a custom DHCP server which can be modified if
necessary.

Thanks in anticipation

PS. Once I have a solution to this problem I will be able to test
Timothy Legge's Broadcom 5721 patch.  This is the onboard NIC for the
Fujitsu-Siemens TX150 S3.
