So if the Two Kernel Monte patch was combined with the system suspend/resume in swap patch then you add some transitions so that the code path does this:
1- Suspend->Monte 2- Monte->Load new Kernel 3- Load->Resume.
If it was just for very similar kernels, i.e. most -pre and -ac kernels it would probably work fine. If not, then you could just do the Monte route.
