At the risk of being flamed by all the 68K lovers, I must point out that the
Intel 286 has stack overflow detection "for free" as part of their segment 
management (and may also have dedicated stack overflow/underflow detection);
it can be used by setting the stack limit <64K, and when the stack overflows
to 64K, you get an segment limit exception.
