Check some example code here: http://www.210computing.com/google/chrome_notifications.html

What powerful influence!
Not sure why didn't go with Growl instead of rolling their own...
HTML notifications can be powerful because they allow you to include live content (video of the person attempting to video chat with you) and actions (e.g. archive, reply buttons) if you choose.
It's not inconceivable that someone could write something that suppressed and stripped the text out of a Chrome notification and presented it in a Growl notification.
You can test the feature in Chrome here:

edit: Just got the permission banner in gmail now - works fine.
