Thanks, Westend.
I've checked those gaps again - when drilling for another bracket - the gap is less than 1/8". So I will go with your suggestion, 1.5" screws, this will give me 3/4" grip in the stud alone, plus 1/2" grip in the particle board. So the screw will not go the last 1/4" or so in the stud.
The pilot hole will still penetrate the 1.1/8" stud completely. It's difficult to calculate precisely the length of the pilot hole required, when the gap is known only approximately.
