The module is probably the tg3 module - Barry already replied that it's
a problematic card and I wholeheartedly agree. I recently gave up trying
to get a new Dell working with this NIC. If you really want to try you
will need to modify the file in /tftpboot/lts/pxe/pxelinux.cfg that
corresponds to either the MAC or IP of this machine. The file that will
correspond to the IP above is: C0A80004.

An example of my file for a machine with this NIC:

prompt 0
label linux
 kernel vmlinuz.ltsp
 append root=/dev/ram0 rw initrd=initramfs.gz NIC=tg3

And in lts.conf:

[00:1E:C9:36:5D:F5]
        MODULE_01 = tg3

This uses the MAC address of the machine, but you can use the host name
or IP as well.

And if none of these steps/entries work then get the card that Barry
recommends. It will save you hours/days/weeks of frustration. :)
