I think it is fine to change the default, but I'm not certain that this fixes
the panics on resume.  So far no one has reported back that this did fix them
after I suggested it.  It would be good to fix the panics as well if possible.
The last time I looked at it in detail, it seemed like the callout for only
ttyv0 had been zero'd.  Other ttyv timers used in switching still had the correct
contents.
