The main difference is the substitution of the Atmel ATmega8u2 in place of the older FTDI chip. The '8u2 has been programmed to act like a USB-serial converter. The second difference is the new bootloader which takes up only 512b compared to the original 2k, and is faster. Other than that they aren't notable differences.

Arduino Uno is the latest version of Arduino Duemilanove.
There are more of similarities between the two so that with no questions a Arduino Uno can be used in place of Arduino Duemilanove.
The few slight differences can be listed in the link below.
