Quote from man page:

Normally,  if  kernel-package  does not find a .config file in the current
       directory, it tries very hard to get an appropriate one (usually a con-
       fig  file  already  tailored for Debian kernels for that architecture),
       and then calls make oldconfig to let the user answer any new questions.

So if you apply the RT patch, make-kpkg will ask you about preemption model.
