Arduino UNO and Arduinome!

Hi guys, i'm building an arduinome, a monome clone based on Arduino. The project is based on Arduino Duemilanove, but in my city (Turin, Italy), i've found only the UNO version. In the final part of the instructions, i must flash the FTDI chip to obtain this fixed serial "a40h-001". My problem is that Arduino UNO does't have the FTDI but the ATmega8U2 and the arduinome software doesn't recognise that. Is there a method to obtain the same results with my arduino UNO?

Thanks in advance! and sorry for my english!
