3Com 3C905's of any vintage also work very well in EtherBoot mode.
That's mostly what I use, along with one Realtek 8129.

I still have one Pentium-I MMX computer around, and it's a great thin
client. I can play full-screen TuxType on it with no slowdowns. Same
for full-screen video. Why? Because it's got a good video board
(Matrox Millenium G400 AGP) and 100Mbps Full-Duplex network card (3Com
3C905 series). Both of these points are very important for performance.
My fastest thin client is an AMD K6-2 running at 450MHz with 256MB
DRAM. Otherwise, it's equipped the same as the Pentium I. Also works
great. A third client runs an ATI Radeon 7500 AGP video board--not
quite as fast as the Millenium, but still good enough.
The Pentium I has a SoundBlaster 16 ISA video board. The K6-2/450 has
an Ensoniq AudioPCI. Both work great.
Unless you're running apps locally, you do not need a lot of CPU on your
thin clients for K12LTSP 5EL. That's one reason I'm sticking with 5EL
for a good, long time, at least on my production network.
