Can I Use an Atmega328 PU loaded with UNO bootloader in a Arduino Deumilanove ?

Can I Use an Atmega328 PU loaded with UNO bootloader in a Arduino Deumilanove board ? I have accidentally destroyed my atmega328 PU on deumillanove board. So I want to replace the micro instead of buying a new board. But atmega328 with duemillanove bootloader is hard to find. So can I use one with UNO bootloader?

Absolutely. It makes perfect sense. Just remember, for the purposes of the IDE, it is now a UNO.

You will of course, still use the FTDI driver in Windoze (doesn't matter at all in LInux).
