This is good news for Adsense publisher from google as reported by Jennifer Slegg in her blog that you can now run AdSense on the same page as other contextual ad programs.

The Official News state as follow;

Publishers are still welcome to place images above the ads. The only exception is if it’s in such a way that it looks like the images are part of the ads.

When something like that comes to our attention, we’ll ask that the publisher place a visible border between the ads and the images, to make it clear that the images are not being served by Google on behalf of the advertisers. We generally do not ask publishers to remove the images completely, we just ask that they add borders to avoid confusion.

Google allow publishers to display even competing contextual ad units, alongside AdSense, as long as they don’t look like Google’s ads.
