It doesn't need to be a re-writing time thing. You can get to the same end result by just saying Hurt did some terrible shit in the name of ending the war, and stopped going by the name of The Doctor in the process... then he died, and regenerated into Eccleston, who was so appalled by what he'd done that he basically disowned Hurt completely, and made his entire existence this big secret.. and lived with the shame of it, which is where we meet him in Season 1.
I don't think it needs to be this complex thing where Hurt was the 9th Doctor, but Ecclestone was the 9th Doctor as well, but then time was rewritten, and this and that... just make it that Eccleston was the 9th "Doctor" but the 10th incarnation of the character.
It's not as if he goes around calling himself the "11th Doctor" and stuff in-story. The numbering has always been more for the fans' than anything in-story. And in the finale, he even says that Hurt didn't hold the title of "Doctor".
I imagine, given the costuming, that Hurt is the 9th Doctor. Most likely the story will be kept simply and focus on that the Hurt Doctor basically was self referred to other than as The Doctor as he choose to commit genocide to end the Time War. The 8th was drafted as were all other Time Lords living or dead as the High Council became desperate. They did bring Rasalon out of his tomb and made him their leader again. They brought back The Master complete with a new set of regenerations. The Doctor may have been press ganged into the war and due to his knowledge, was made a general. Possibly forced into a regeneration as well or injured during the war causing the regeneration.
With this upcoming special, we will likely see the events somehow cause the regeneration into the Eccleston Doctor after having encountered the Tennant and Smith Doctors.
I suspect this is also a way to springboard into dealing with the whole limited number of regenerations rather then leaving it for the future.
Remember, there are several escape hatches on the number both in the classic and the modern run for the Doctor to have more lives.
