Yes, the Arduino Power LED is on, notice that the code was written for Duemilanove, but experts say that it should work ok. Another info you need to know is that other sketches all work without any problem.
Duemilanove and Uno use same 328P chip, so no difference running on either board type with code generated for either one. Only if total compiled code size is nearly filling the chip can there possibly be a difference as the Uno has a smaller code size bootloader so a slightly larger sketch can be loaded Vs the Duemilanove board.
