Here's a script that takes the list of modules and pcimap from the kernel
packages, mixes it with the description from pci.ids to produce a
ethpci.list for ddetect.

The advantage of this is that for all the PCI network devices that we
actually have modules for, we are guaranteed to have an entry in this
list with the correct module name.  It's also true that we won't have
an entry in this list if the card is not supported by one of our modules.

The modlist file can be obtained by doing

cat modules/nic-modules* > modlist

in an unpacked kernel-image-2.4.19-i386 source tree.

The resulting list when run against 2.4.19-3 can be downloaded from
