I've made an Ethernet shield compatible with the official one on
through-hole components.

Project description
This project was introduced on forum.aduino.cc by ID systems Sept 2011.
The author made a DIY W5100 ethernet shield compatible with the official one on through-hole components.
Works well just like the original Ethernet shield. Schematics are similar to the official one,
The Author has 47nf cap on RST line to avoid the reset problem with W5100 related to ARDUINO.
The author had to reference Wiznet's reference schematics, Ethernet shields from
Arduino and Freetronics and had to learn about PCB routing.
Once you solder the 0.4mm-spaced LQFP chip
The author used gEDA suite to produce board schematics and layouts, which required little custom symbols to be made. I've attached the schematics image.
The second revision was under construction at this posting (he hopes to get PCB's manufactured by summer).
A better main board with SD card, DS1307 and slots for radio modules (RFM23 and simple ASK TX/RX modules) is in the works too, pic related.
I'm doing this for yet another house automation system.
I'll post schematics and gerbers when it's done.
This post was forced to wake up by the comment which was the question of W5100.
Read this article, it is very useful for HW ethernet makers.
