Increasing KSTACK_GUARD_PAGES may help ensure that an under-dimensioned
kernel stack size blows up correctly (though this will mean tweaking
/sys/i386/include/param.h directly because it's not a configurable
parameter).

As another suggestion: I presume the kernel stack is pre-zeroed.  If
so, it would be not overly complex to have a task (user or kernel)
that regularly checked how much stack was used for each stack and
flagged ones that were excessively deep - which would give you an idea
of the actual usage.
