Hrrrrmm.  I don't see anything obvious in either the driver or the userspace 
program that could cause a trip up here...

Can you check the user space watchdog daemon is running? (as root)

Not in dom0, although this would be the case in other domains.

You did run this with root privileges, right?

Cheers,
