Make sure we only handle the DraCo native timer interupt, if it was enabled. 

We test this condition AFTER the interupt condition, because it is only
disabled during autoconfiguration.
Without this patch, if autoconfiguration takes long enough, eventually a
timer interupt will call hardclock() and panic the machine.
