Ok, I will try to shift the intercepts in an uint_64 flags variable in the TB.OK, great.

I actually don't see too much of a performance penality in that but nevertheless could you please test if the appended patch hits performance for you? This changes the tb->flags field to be 64 bits.
If it does not, please apply this to the CVS as my SVM patch now relies on it.
