I got a dictionary working, following Polvo's directions here:

Important! When searching for a dictionary, under Other Options, you have to select StarDict format.
I chose The Collaborative International Dictionary of English v.0.44
Works great! And has the audio, also. That right, some little guy inside the Kindle reads your word for you. Thanks, Polvo!
