  The emergence of quantum-gravity induced corrective terms for the probability
of emission of a particle from a black hole in the Parikh-Wilczek tunneling
framework is studied. It is shown, in particular, how corrections might arise
from modifications of the surface gravity due to near horizon Planck-scale
effects. Our derivation provides an example of the possible linking between
Planck-scale departures from Lorentz invariance and the appearance of higher
order quantum gravity corrections in the black-hole entropy-area relation.
