Having the watchdog still allows you to enter DDB. Think one step ahead:
certain ICH6 generations can't reboot the system, but are not detectable
by software. The Thinkpad R52 had that problem. Either the watchdog API
should allow to specify what types of watch dog actions are (not)
possible or it needs to be exported via side channel. The functionality
of the hardware is still useful.
