~he implementation of the WD_PASSIVE part is on my list.

I don't quite agree with you on the kernel taking over though. When 
testing watchdogs you should be able to see that you could not disarm 
it, as you would otherwise get mysterious hard reboots. I'd rather have 
watchdogd refuse to exit if it cannot disarm the watchdog. I'll put that 
on my list too.
