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.
