Let's see if this works this time 
I was playing ME2 again while keeping an eye out for IT-related things. I found some evidence that relates to the whole 1M1 thing.
The crashed geth ship in Overlord (doors added by Cerberus)
A box inside the derelict Reaper (brought by Cerberus)
The Reaper IFF room (presumably constructed by Cerberus)
The Normandy SR-2 (you get the idea)
First thing I noticed is that all of these text and number sequences are reversible and/or inversible. Considering how often assets get reused, I'll attribute that trait to savvy design staff at Bioware. Second thing I noticed is that all of these objects are related to Cerberus. The designs are also aesthetically consistent with the 1M1 assets (which I may note have Cerberus colors).
Furthermore, Cerberus would almost certainly use human contractors and companies to provide materials for such clandestine operations as Overlord, excavating the derelict Reaper, and rebuilding the Normandy. The Illusive Man was able to learn about turian technology via their collaboration on the Normandy SR-1, so he would be cautious about giving other races the same opportunity.
This leads to the question: why does a portion of the Citadel which no one has ever seen before have human-built components? Keepers salvage things all the time to repair the Citadel, but the 1M1 struts are huge, fully-intact, and look completely brand new. Once we take the IT into consideration, we can see these design elements as something incorporated into the hallucination by Shepard's mind.
Obviously, these findings won't revolutionize the IT or convince new people to listen to us, but they do offer some interesting speculation and something else to throw on the mountain of circumstantial evidence.
Interesting, I have suspected for awhile that we haven't heard the last of Cerberus and if the ending didn't actually happen then TIM is probably still around, scheming or something. There's also that rumour that Wong stumbled across regarding Cerberus in London prior to the invasion of which I still can't find in the codex but know I've read it some where. And there are all those weird signs that point to Coates not being who he says he is... maybe he's a Cerberus agent.
Or (and this is the pessimism speaking) these are all left overs from the previous incarnation of the ending before it was drastically altered (that is, the one referred to in the artbook and the Last Hours app regarding a final showdown with TIM on a Cerberus base). For that matter, a lot of clues we've found may be remnants of a dropped plot device. Would like to be wrong about that, they wouldn't be that sloppy, right?
