Turns out I didn't... and you didn't need to... emaste helped me
the other night discover this.. Apparently rwatson changed this and
the docs never got updated... I saw BREAK_TO_DEBUGGER, bug it was
documented as being *serial* only, not syscons...
I've updated NOTES and added an entry for defaults/loader.conf, but
more docs need to be updated that BREAK_TO_DEBUGGER or the tunable
or sysctl needs to be set before if works..
