I have just created a new site similar to Kongregate or GameGum, called www.FlashGameALot.com. I have a very simple way of sharing revenue with game developers: You enter a google adsense publisher code, and 50% of the time that your game is shown on my site, it will use your adsense code. You also get a backlink to your site on the game page. So why not submit a game or two and see if it does anything for you? This is a new site that I am experimenting with, so I encourage comments and suggestions as to how it may be improved (I realize it is quite minimal right now, but this may change in the future).
