Joe/All,
I'd be cautious using this technique. If the binder ears have bent inward enough to touch, the lack of seatpost clamping force is only 1/2 of the problem, which relieving the binder ears does solve. The other problem is that the hole in each ear is no longer parallel and co-axial. This causes the binder bolt to bend as it is tightened, and can cause failures just like non-parallel rear drops can cause hub axle breakages. I have preferred to try to set them back in place by using a stout round-shaft screwdriver (or similar) for leverage, or by prying outward from the slot side with a stout flat-blade screwdriver. These techniques have downsides, too, though. The binder bolt hole or slot edge can get distorted from localized pressure. I always try to use the largest tool possible in each case.
