On critical overheat (or perceived critical overheat -- acpi bioses on some notebooks apparently report bogus values from time to time), kernel itself calls /sbin/halt *without telling anything*. User can not see anything, his machine just shuts down cleanly. Bad. We should at least tell the user what is going on...
