It is being met by watchdog timers, which cause reset unless the software resets them frequently enough. Several microcontrollers implement watchdog timers.
If other people haven't found a working option in Linux by now, I'd look for embedded Linux versions, see how they implement this. Maybe they have a driver whose source code can be incorporated in stock Linux kernel.
I'd look also for a watchdog timer plug-in card for a PC (no idea if one really exists).

What I'm looking for is a kernel command option (I can put it in lilo.conf) that tells it "if you panic, just reboot". This will save me the phone call in the middle, and yeild much more robust behaviour.
Anyone know of such an option?
I don't know of such an option. Isn't a kernel panic just that, a
situation where it sits and does nothing because of total confusion or
shock?
Perhaps one should look to make the initrd more smart in the sense
that it will *check* whether it will be able to mount the prescribed root partition so that it will reboot the machine if it can't?
What about asking the ISP operators to connect one phone line to the
machine for an hour or so?
