To say that one is homosexual in orientation, yet vows to remain celibate, is not "openly homosexual." It is perfectly possible for a man to be homosexual, yet not define himself by his homosexuality as some homosexuals seem to do.
Now, given Pope Benedict's positions against homosexuality, why do you think he would suddenly open the door to avowed homosexuals.
Again, an "avowed homosexual" would seem to be excluded by the third criterion I listed above, that is, one who is "irrevocably committed" to the homosexual lifestyle.
I am speaking of celibate homosexuals who do not act on their homosexuality.
I can't answer for Benedict XVI. But, I suspect the exceptions made will be made at the insistence of local bishops, who are aware they have a significant number of celibate homosexuals serving in their dioceses as good priests.
But an admitted homosexual is currently barred from ordination by the 1961 Papal Ban. Pope Benedict would have to overturn all of Church history.

As you said, the document in question will only affect seminarians, not priests.
There's also this:
In an interview published in the New York Times Sunday, Pope John Paul II's spokesman Joaquin Navarro-Valls cited canon law on homosexuality and said, "People with these inclinations just cannot be ordained."
It seems like the Vatican's position is pretty clear.
Here's an article refuting those rumors (not from the MSM, which are all pro-homosexual):

Then there's the bishops who believe that homosexual seminarians are keeping straight men away from the seminaries. To whom would the Pope listen?
