How can I get Quicksilver to open bookmarked URLs in Chrome? I'd like to be able to trigger QS and then start typing "gmail" or "weather" or the name of whatever bookmark I'd like to open, and have the previously bookmarked site open in Chrome, my default browser. Is it possible to do this with Chrome? 

(I was able to do this with Quicksilver on my old G5 Mac, although I used Firefox on that machine.)
There is now a Google Chrome plugin for Quicksilver (with documentation). Version 1.0 was released on April 27, 2012.
