Hawking radiation and negative gravitational charge

[YummyFur]

The idea rests on the hypothesis that particles and antiparticles have gravitational charges of opposite sign.

I was wondering if virtual anti particles had a postulated anti gravitational charge if that would be inconsistent with Hawking radiation as virtual anti particles would always be ejected from the vicinity of the Schwarzschild radius whereas virtual particles may or may not be ejected depending on the direction of their momentum.

There is a fundamental problem with your question, which is this: the "particle / anti-particle" explanation of Hawking Radiation is not an actual description of what happens. It is a heuristic posited by Hawking himself, who described it as being simply the best he could come up with to explain in English something that really can only be explained in the math.
