I've been using Spot's Chromium repo to keep up to date, but apparently
nobody has been working on it as of late.
The "stable" version is 13.0.782, which is marked as "old" on
http://en.wikipedia.org/wiki/Google_Chrome#Release_history and the
"unstable/trunk" is 14.0.827, which is just a few revisions shy of
current stable Chrome release.
