How about putting a select box behind a text box, and having an onChange method on the text box that ajax's up the suggestions and puts them into the select box? Not sure if you can programatically open up a select box mind.
I did not actually write the original question. I assume one of my coworkers did this while sitting at my console.

There's some plausible deniability if I've ever seen it. ;-}
