Has anyone determined whether the deadline for adopting a corrective amendment under 1.401a4-11g (10/15/03) is extended until 11/18/03 due to Hurricane Isabel?

I have a possible 410b and 401a26 failure in a 2002 calendar year DB plan.

Rev Proc 2002-71, Sec 5 item 15 extends the deadline for 401a failures due to disqualifying provisions but I am not sure if this is on point or if there is something else that extends my deadline.
