The room where Wolverine is having his "procedure" is exactly the same as in X2, so I don't think they'll just be ignoring the other movies. The scense with young Storm, Cyclops, Emma etc could take place in flashback and the Gambit stuff in present day. And maybe Wolverine will give Sabretooth a lobotomy with his claws at the end or something.
I realize that Sabretooth having a much bigger role necessitate them casting a "real" actor, but will they just ignore Tyler Mane's version from the first film??
One way they could get around it is simply have Schreiber be the "original" Sabertooth, and have the Tyler Mane one just be some lunkhead with similar abilities who adopts the name later on.
