Did you had a look at ethernut? Something very useful is already there. This project
looks always for contributors.
To your question:
if an interrupt occurs your kernel has no chance to save any registers. so the pro/epilogue is very helpful.
your kernel will be interrupted and it is not clear -- when.
Look at the ethernut-way: it uses a kind of wrapper for any possible interrupt source available.
and if you attach an real interrupt-handler to it, it will be called.
Hopefully I understand your question right...
