I think Jean has the descriptions backwards, at least as Winbond has documented it,
and we copied that terminology into the documents doc/developers/proc in our package,
and i2c/sysfs-interface in the 2.6 kernel.
The lm_sensors standard is that alarms are persistent ("don't wear off automatically")
which Winbond calls "comparator".
Drivers should configure the hardware for that mode (whatever it's called).
