How often do you go into the attic? If you don't go up too often you could try some removable caulking. I use it on an attic door to my knee wall because I had an energy audit that found the V-gasket that I used was nearly worthless and the gap is too thin for anything else, works great. I'm also going to seal up my 3 foot by 2 foot attic opening that pushes up with the same stuff.

I'm not sure what your attic stairway looks like but would something like this help? Owens Corning AS2 Attic Stair Insulator R-10

It might only be R10 but something like this and some removable caulking would be under $50 and likely pay for itself over a fairly short period of time. The caulking could be used in other places too if there are other things that need to be sealed off.
