It is not supported off the shelf. 

We (Cyclades) have a timer to periodically touch the watchdog on boot, and afterwards
a watchdog driver which gets periodically written by a userspace daemon. 

I can send a patch if you wish.

Hi,

I wonder if someone could help me with answering couple of my questions:

How watchdog resetting is handled for PPC 
in Linux 2.6 on the kernel level ?
Does one need to add code for it or is it supported "off the shelf" ?

Is "early printk" supported for PPC on 2.6 ?
If yes - how and where it could be enabled?

Thanks,
Alex
