Hi,
Version 5 is compatible with the Arduino Mega 2560. The PCB has an ICSP connector at the bottom to reach the right pins i believe.
This is from the shield page (i couldn't post a link, 1st post?)
- 8< ----
It is compatible with the Arduino Duemilanove and Mega (using the Ethernet library coming in Arduino 0019) - 8< ----
I'm using these 2 boards myself without modifying anything
Sooo.... NO pin bending needed
