eepro 100s are really among the best performing cards. Part of our
infrastructure involves some routing on FreeBSD and we swear by these in such
machines.

The Tyan Tiger 2466 MPX board has an onboard 3com 3c905 ('vortex') card
with PXE and RPL on it. (The ECS K7S5A which may be similar to the K7AMA
has only RPL. There are RPL daemons for linux but support is experiemental
at this point. Also note there's support for the IBM (I think?) version
of RPL for linux and not the Novell version. Someone out there may be
more clear on this, but RPL is a bit of a mess.) The tiger boards are
really sweet in that they have on board serial console and 2x 64/66 PCI
slots. And its only a bit more than twice the price of a single athlon
board, but you get to save space and power. Im extermely happy with mine
so far.
