Amber 11 with bugfix.12 has

static const int SM_2X_LOCALFORCES_THREADS_PER_BLOCK = 256;

instead of 256 which provides the stability on GeForce cards (no lockups
reported since this change) and has minimal impact on performance. For the
development code however, the ifdef is required and will (I hope) be
automated for the main release.

All the best
Ross
