Great idea but I would immediately leave a site like that. I don't have time to go thru a lot of ads just to find info.
The blog is owned by http://www.b5media.com/ in which has there traffic stat's posted on that page. Look at the "DID YOU KNOW" box for the companys stat's. With those stat's, i am sure they are a premioum publisher or google gave them permission to add more ad unit's. This just my 2 cent's. Please ignore me. It's my birthday for another 2 hours so i need to drink more.
There are 180 sites using the same google adsense id so I think it's safe to assume the owner know something you guys don't see it.

This is defiantly against Google's TOS and they will be banned very soon when Google finds out what they are doing. Google's Terms indicated clearly that only 3 adsense units maximum are allowed on one page.
That's cool. I have always wanted the 125x125 adsense one but i am not a premium publisher and will never be one. lol
