Are you ABSOLUTELY CERTAIN nobody in the Pakistani Government was informed of the mission?
The case they did:
Pakistan does have an air defense system, even if its main purpose is to defend against attack from India. How likely is it that drones provided surveillance of the bin Laden compound for some time during the planning for attack and that five helicopters sneak into Pakistan airspace with no one shooting anything down?
The case they didn't:
In truth, there's been a very soft arms embargo against both India and Pakistan since they conducted nuclear tests (with the emphasis on very soft) until Pakistan committed itself to joining the fight against terror; at which point it became easier for both Pakistan and India to purchase weapon systems. While both were able to obtain some weapons and Pakistan was able to even upgrade its existing air defense system, Pakistan's air defense system isn't among the strongest systems in the world (Iraq, Serbs, and Libya all had better air defense systems than Pakistan).
Additionally, Pakistan's main threat is from India and the strength of their air defense system has been deployed to protect against them; not against Afghanistan (although there have been rumors that Pakistan has or has at least intended to install an air defense system to protect the Afghanistan border against drones - having US military aid go towards protecting the border from US drone attacks would be ironic, if it actually happened).
Pakistan purchased a modern air defense system from Italy and tested it in 2010, but it hasn't come online operationally, yet.
Additionally, http://seattletimes.nwsource.com/html/nationworld/2015080215_osama18.html and jamming to evade air defense systems. Perhaps even the stealth helicopter part is true.
The case they did know:

Drones have been violating Pakistan's airspace for years - a condition that's seen as preferable to having Pakistan's borders violated by actual people on the ground.
There's just no way to really know.
Having Pakistan's leaders deny knowledge of the attack instead of share credit for the attack does seem like the more damaging path. It humiliates Pakistan's military - one of the few Pakistani institutions that has credibility with Pakistan residents. On the other hand, money from the US for weapons is quickly rectifying any weaknesses in Pakistan's air defenses, so any humliation of the military will be short lived.
I think sharing responsibility for the raid also carries a serious backlash for the Pakistani government and perhaps that really would be the more serious (or at least more violent) reaction.
To me, there's just too much "magic dust" used in this raid for Pakistan's denials of knowledge to be enitirely credible, but, like I said, there's just no way to really know.
