The number of incompatible kernel/module interface changes per kernel is
most likely some medium three digit number.
What you have in mind is therefore not really feasible.
But we have several levels of kernels that incorporate future stuff,
from -rc over -next to -mm, and you could implement automated runs
of the systemtap testsuite against the latest ones.
