Triggering For Auld Lang Syne? (Spoilers, I guess)

[Loona is Hot]

So, I'm having a bit of trouble getting this quest to trigger.
My understanding was Arcade Gannon would offer this quest if I met either of two criteria - have 2 trust points and have The house always wins V/For the Republic! II/Legion thingy/Yes man thing quests active OR have a total of 5 trust points and be at any point in the game.

Am I understanding correctly?
I've ammased around six or seven trust points by my count and I still have yet to be offered the quest. Is it a random thing? Is it "If they have >5 trust points there's a CHANCE I'll offer the quest"? Is it simply a matter of waiting some time, or do I need to re-assess my situation.

You need to do some things with his "group" also.. This is a snippet from my faq that you can look at and see what you've done and haven't done yet. Hope it helps..

Pick up ARCADE GANNON and
talk to him. We need to visit a few locations with ARCADE to set up
his quest, so fast travel to the following locations and let him talk
while hes there.

1) CRASHED VERTIBIRD.. beware, robots are about so go in weapons blazing.
2) REPCONN HEADQUARTERS. enter the building for him to comment.
3) THE FORT. kill a couple re-spawned LEGION. When ARCADE talks answer
"Lets just listen to him...."
4) DR. HILDERN in CAMP MCCARRAN. Talk to HILDERN a little, then when
ARCADE talks answer "Good thing there are people like you.."
5) WESTSIDE. Once entering he talks, answer "If you say so.."

) Fast travel back to THE STRIP and talk to MR. HOUSE. You will now have to
take out the BROTHERHOOD OF STEEL.

) Head to HIDDEN VALLEY, making sure you are stocked up with a temp SCIENCE
skill book (You'll need 100 science check). Enter the base, at the first
entrance room of PALADIN RAMOS you can turn the Gun Turrets in the base
on the BROTHERHOOD.

) Let the Gun Turrets clear out some BROTHERHOOD (loot them) then at the
2nd level enter the generator/virtual room and access the [SCIENCE:100]
check terminal to turn on the self-destruct. Now you have to fight your
way out of the base. You might as well clear it out and loot it since you
won't be back.

) Return to MR. HOUSE to report. Fast travel to HOOVER DAM, and ARCADE will
stop and talk. We now need to round up his old ENCLAVE soldiers to help
against the LEGION.

It has some info that might help you, dont' think you need to do that middle part (mr house and brotherhood destruction) but his conversations at certain areas, etc.
